HD66789
Preliminary
Description
The HD66789 handles 262,144 TFT colors and can drive a TFT color liquid crystal display of 176 RGB x 240 dots with an incorporated RAM compliant to graphics display of 176 RGB x 240 dots at maximum, and a 528-channel source driver outputs. The HD66789 incorporates a gate driver and a power circuit for driving liquid crystal display to drive a TFT panel with a single chip. The HD66789's bit-operation functions, 8/9/16/18-bit high-speed bus interface, and high-speed RAM-write functions enable efficient transfer of data and high-speed data update on a graphics RAM. The HD66789's 6/16/18-bit RGB interface (VSYNC, HSYNC, DOTCLK, ENABLE, and PD 17 to 0) and VSYNC interface (system interface + VSYNC) provide an interface for moving picture display. With a window address function that facilitates the moving picture display in an arbitrary area and enables simultaneous display of moving pictures and the contents of the internal RAM, the HD66789 enables moving picture display not constrained by the still picture area. Accordingly, the data transmission is reduced to minimum, thereby saving power consumed by a system as a whole when displaying moving pictures. The HD66789 supports power-saving operation up to the power supply voltage of 2.4V with a voltage follower circuit that generate voltage to drive liquid crystal. The HD66789 also incorporates 8-color display and standby functions that allow precise power control by software. These features make this LSI the ideal solution for any medium or small-sized portable battery-driven products such as digital cellular phones supporting WWW browsers or small PDA, where long battery life and board size are major concern.

Preliminary
Block Function
1. System Interface
The HD66789 has five high-speed system interfaces: 80-system 18-/16-/9-/8-bit bus and Serial Peripheral Interface (SPI) port. The interface mode is selected with IM3-0 pins. The HD66789 has three registers: 16-bit index register (IR), 18-bit write-data register (WDR), and 18-bit read-data register (RDR). The IR stores index information from control registers and GRAM. The WDR temporarily stores data to write into the control registers and GRAM, and the RDR temporarily stores data read from GRAM. Data written into GRAM from the MPU is first written into the WDR and then automatically written into GRAM by internal operation. Since data are read through the RDR from GRAM, the data read out first are invalid data and the ensuing data are read out normally. The execution time for instructions other than oscillation start is 0-clock cycle, which enables consecutively writing instructions. Register Selection (8/9/16/18 Parallel Interfaces)

HD66789 2. External Display Interface
Preliminary
The HD66789 incorporates RGB and VSYNC interfaces as an external interface for displaying moving pictures. When RGB-I/F is selected, the display operation is executed in synchronization with the externally supplied signals, VSYNC, HSYNC, and DOTCLK. The display data (PD17-0) are written according to the values of the data enable signal (ENABLE) and data valid signal (VLD) in synchronization with VSYNC, HSYNC, and DOTCLK signals. This data write method allows flicker-free screen update. When VSYNC-I/F is selected, operations other than the frame synchronization by VSYNC signal are synchronized with internal clocks. The display data are written to GRAM through a system interface. In this case, there are constraints on the timing and methods of RAM update. See the "External Display Interface" section for more details. Switching between conventional system interfaces and external display interfaces is made through instructions. An optimum interface is selected whether the screen is displaying moving or still pictures. All data written through RGB-I/F are written to GRAM. Therefore, data is transmitted only when the screen is being updated, which reduces the amount of data transmission, thereby saving power when moving pictures are being displayed. 3. Bit Operations
The HD66789 supports a write data mask function that selects and writes data into GRAM by bit, and performs logical operation or conditional rewrite on the contents of compare registers and the data to write to GRAM. For details, see the "Graphics Operation Functions" section. 4. Address Counter (AC)
The address counter (AC) assigns address to GRAM. When an address set instruction is written into the IR, the address information is sent from the IR to the AC. After writing data into GRAM, the AC is automatically updated plus or minus 1. The AC is not updated when the data are read from GRAM. Window address function enables data write only in the rectangular area of GRAM specified by the window address. 5. Graphics RAM (GRAM)
GRAM is a graphics RAM that stores bit-pattern data of 176 x 240 bytes with 18 bits per pixel. 6. Gray scale power supply voltage generating circuit
The grayscale voltage generation circuit generates liquid crystal drive voltage according to the grayscale data set in the -correction register, enabling 262,144-color display. For details, see the "-Correction Register" section. 7. Timing Generator
The timing generator generates timing signals for the operation of internal circuits such as GRAM. The timing for display operation such as RAM read and the internal operation timing such as access from MPU are generated in a way to avoid mutual interfere. The interface signals (M, FLM, CL1, EQ, DCCLK,
Rev.0.12, May 09 2003, page 19 of 156
HD66789
Preliminary
DISPTMG, and SFTCLK) are generated internally, and a part of the signals is output through a level transforming circuit. 8. Oscillation Circuit (OSC)
The HD66789 can provide R-C oscillation simply by placing an external oscillation-resistor between OSC1 and OSC2 pins. An appropriate oscillation frequency for operating voltage, display size, and frame frequency can be obtained by adjusting the external-resistor value. Clock pulses can be supplied externally. Since R-C oscillation is halted during the standby mode, current consumption will be reduced. For details, see the "Oscillation Circuit" section. 9. LCD Driver Circuit
The LCD driver circuit of HD66789 consists of a 528-output source driver (S1 ~ S528) and a 240-output gate driver (G1 ~ G240). Display pattern data are latched when 528-bit data arrive. The latched data controls source driver and generates drive waveforms. The gate driver, which operates display scan, selects either VGH or VGL level to output. The shift direction of outputting 528 bits from source driver is changeable with the SS bit. The shift direction of gate driver scan is changeable with the GS bit. The scan mode of gate driver is changeable with SM bit. Select an appropriate shift direction and mode for an assembly. 10. Liquid crystal drive power supply circuit The LCD drive power supply circuit of HD66789 generates voltage, V0, V31P, V31N, VGH, and Vcom required for driving LCD.

HD66789
Preliminary
Instructions
Outline The HD66789 adapts 18-bit bus architecture that enables high-speed interfacing with a high-performance microcomputer. Data sent from external (18/16/9/8 bits) are stored temporarily in the instruction register (IR) and the data register (DR) to store control information before internal operation starts. Since internal operation is decided according to the signal sent from the microcomputer, register selection signal (RS), read/write signal (R/W), and internal 16-bit data bus signal (DB15 to DB0) are called instruction. GRAM is accessed through internal 18-bit data bus. There are eight categories of instructions: 1. 2. 3. 4. 5. 6. 7. 8. Specify index Read status Control display Control power management Process graphics data Set internal GRAM address Transfer data to and from internal GRAM Set grayscale level for internal grayscale -adjustment
Normally, the 7th instruction to write display data is executed the most frequently. The address of internal GRAM is updated automatically after data are written to the internal GRAM. With the window address function, this reduces the amount of data transmission to minimum and thereby lightens the load on the program in the microcomputer. Since instructions are executed in 0 cycle, it is possible to write instructions consecutively. As the following figure shows, the assignment to the 16 instruction bits (IB15-0) varies according to the interface in use. An instruction must adopt the data format for each interface.

Instruction bits Instructions The following are detail explanations of instructions with illustrations of instruction bits (IB15-0) assigned to each interface. Index The index instruction specifies the index (R00h to R4Fh) of control register and RAM control. It sets the register number from 0000000 to 1111111 in binary form. Do not try to access to the register to which the index is not assigned.

Start Oscillation (R00h) The start oscillation instruction restarts the oscillator in a halt state during the standby mode. After executing this instruction, wait at least 10 ms for stabilizing oscillation before issuing a next instruction. For details, see the "Standby Mode" section. "0789"H is read out, if this register is forced to read out.

SS: Select the shift direction of outputs from the source driver. When SS = 0, the shift direction of outputs is from S1 to S528. When SS = 1, the shift direction of outputs is from S528 to S1. In addition to the shift direction, the settings for both SS and BGR bits are required to change the assignment of R, G, B dots to the source driver pins. To assign R, G, B dots to the source driver pins interchangeably from S1, set SS = 0, BGR = 0. To assign R, G, B dots to the source driver pins interchangeably from S528, set SS = 1, BGR = 1. GS: Select the shift direction of outputs from the gate driver. The scan order is changeable in accordance to the scan mode by the gate driver. Select an optimum shift direction for the assembly. SM: Set the scan order by the gate driver. Select an optimum scan order for the assembly. For details, see "Scan Mode Setting".

The HD66789 modifies write data sent from the microcomputer before writing to GRAM. This enables high-speed GRAM data update, and reduces the load on the microcomputer software. For details, see the "Graphics Operation Function" section. TRI: RAM write data are transmitted in 3 times through 8-bit interface when TRI = 1. When 8-bit interface mode is not selected, set TRI to 0. DFM1-0: Specify the data format for the RAM write data transmission when TRI = 1 (8-bit interface mode only). DFM1-0 = "10" : 262k mode (6bit x 3 transmissions) DFM1-0 = "11" : 65k mode (5,6,5 bits transmissions)

HD66789
Preliminary
HWM: When HWM=1, data are written to GRAM in high speed. In high-speed write mode, 4 words are written to GRAM in a single operation after executing 4 RAM write operations. If RAM write is terminated before it is executed 4 times, the last data will not be written. Make sure that RAM write is executed 4 times. For this reason, the lower 2 bits must be set to "0" when setting the RAM address. For details, see "High-Speed RAM Write Mode" section. I/D1-0: The address counter is automatically incremented by 1, after data are written to GRAM when I/D10 = "1". The address counter is automatically decremented by 1, after data are written to GRAM when I/D1-0 = "0". An independent setting for the increment or decrement of the address counter can be made to the upper (AD15-8) and the lower (AD7-0) bits of the address. The address transition direction when data are written to GRAM is set with AM bits. AM: Set the direction of updating address counter automatically after data are written to GRAM. When AM = "0", the address counter is updated in the horizontal direction. When AM = "1", the address counter is updated in the vertical direction. When the window address is specified, data are written to the GRAM area specified by the window address in the manner specified with I/D1-0, AM bits.

D1-0: The graphics display is on when D1 = 1, and off when D1 = 0. When setting D1 = 0, the data are retained in GRAM. This means the graphics is instantly redisplayed when setting D1 to 1. When D1 is 0 (i.e., the display is off) all the source outputs are set to the GND level. This reduces the charged/discharged current on LCD, accompanied by the liquid crystal AC drive. When D1-0 = 01, the HD66789 continues the internal display operation, even while the external display is off. When D1-0 = 00, both the internal display operations and the external display operation are halted. In combination with GON and DTE bits, D1-0 bits control ON/OFF of display.

Setting for external display interface control allows selecting an optimum interface for the kind of display as follows. When displaying a moving picture (RGB-I/F/VSYNC-I/F), the display data must be written in the high-speed mode (HWM = 1) which enables high-speed RAM access with low power consumption.

Note 1) The instruction register setting is made only through a system interface. Note 2) Switching between RGB-I/F and VSYNC-I/F cannot be made. Note 3) The RGB-I/F mode settings is not changeable during RGB I/F operation. Note 4) For details on the transition flow between operation modes, see the "External Display Interface" section. Note 5) Use the high-speed write mode (HWM = 1) during the write operation in RGB-I/F and VSYNC-I/F modes.
Internal clock operation mode All display operations are controlled by signals generated by the internal clock in internal clock operation mode. All inputs through the external display interface are invalid. The internal RAM is accessible only through a system interface. RGB interface mode (1) Display operation is controlled by the frame synchronization clock (VSYNC), line synchronizing signal (VSYNC), and dot clock (DOTCLK) in the RGB interface mode. These signals must be supplied throughout the display operation in this mode. All display data are stored in the internal RAM, transmitted with PD17-0 bits by pixel. The combination with the high-speed write mode and window address function enables simultaneous display of both moving picture areas and the internal RAM area. The data are transmitted only when the screen is being updated, thereby reducing the overall data transmission to minimum. The periods of the front (FP) and back (BP) porches and the display period (NL) are automatically generated in the HD66782 by counting the clock of line synchronizing signal (HSYNC) in accordance to the frame synchronizing signal (VSYNC). Transmit pixel data with PD 17-0 bits in accordance with the setting specified above.

HD66789 RGB interface mode (2)
Preliminary
When RGB-I/F is selected, RAM data are changeable through the system interface. This write operation must be performed while display data are not being transmitted through the RGB-I/F (ENABLE = High). When reverting from the system interface mode to the data transmission through the RGB interface, make a new setting for the address set and index (R22h) after changing the aforementioned settings. VSYNC interface mode The internal display operation is synchronized with the frame-synchronizing signal (VSYNC) in the VSYNC interface mode. By writing data to RAM at a fixed speed on the falling edge of VSYNC, it enables moving pictures display with a system interface. In this case, there are some constraints in the RAM write speed and methods. For details, see the "External Display Interface" section. In the VSYNC-I/F mode, only VSYNC input is valid. Other input signals for the external display interface are invalid. The front porch (FP), back porch (BP) periods and display period (NL) are automatically generated in accordance to the frame synchronizing signal (VSYNC) according to the register setting of HD66789.

BT2-0: Change the step-up scale of the step-up circuit. Adjust the scale according to the voltage. Smaller scale consumes lesser current. DC02-00: Select the operating frequency for the step-up circuit 1. The higher frequency enhances the drive capacity of step-up circuit as well as the display quality, while the current consumption will increase. Adjust the frequency taking both the display quality and the current consumption into consideration. DC12-10: Select the operating frequency for the step-up circuit 2. The higher frequency enhances the drive capacity of step-up circuit as well as the display quality, while the current consumption will increase. Adjust the frequency taking both the display quality and the current consumption into consideration. AP2-0: Adjust the amount of fixed current from the fixed current source of operational amplifier for the liquid crystal drive power supply. When the amount of fixed current is set large, the liquid crystal drive capacity will be enhanced and the display quality will improve, while the current consumption will increase. Select an optimum amount of current taking both the display quality and the current consumption into account. During non-display operation, set AP2-0 = "000" to halt the operation of operational amplifier to reduce current consumption. DK: Control the operation of the step-up circuit 1. When turning on the power supply, stop the start up of VLOUT1 for a moment, and wait for an enough time until VLOUT2 is stabilized before starting up VLOUT1. For details, see the "Power Supply Setting Flow" section.

HD66789
Preliminary
SLP: When SLP = 1, the HD66789 enters into the sleep mode. In the sleep mode, internal display operation is halted except the R-C oscillator to reduce current consumption. Only power control instructions (BT2-0, DC2-0, AP2-0, SLP, STB, VC2-0, VRH4-0, VCOMG, VDV4-0, and VCM4-0 bits) are executed during the sleep mode. No change is made to the GRAM data or instructions during the sleep mode, although it is retained. STB: When STB = 1, the HD66789 enters into the standby mode. In the standby mode, display operation is completely halted, and all internal operation including the internal R-C oscillator and reception of external clock pulse, is halted. For details, see the "Standby Mode" section. Only instructions to release the standby mode (STB = 0) and to start oscillation are accepted during the standby mode. Changes in the GRAM data or instructions during the standby mode are susceptible to destruction. These changes should be made after releasing the standby mode. VC2-0: Adjust the reference voltage for VLEG1OUT, VciOUT voltages to the optimum ratio of Vci.

PON: Start operation of VLOUT3. To stop operation, set PON = 0. To start operation, set PON = 1. VRH3-0: Set the scale for amplifying VLOUT1 voltage (the reference voltage for VCOM and grayscale voltage). REGP voltage is amplified by 1.33 ~ 2.775 times. VCOMG: When VCOMG = 1, VcomL outputs a negative voltage (1.0V ~ -Vci+0.5V Max.). When VCOMG = 0, the amplifiers for the negative voltage is halted, thereby saving power consumption. When VCOMG = 0, settings with VDV4-0 bits are invalid. In this case, to adjust AC amplitude of Vcom, make settings with VCM4-0 bits (VcomH setting). VCOMG = 1 is valid when PON = 1. VDV4-0: Set the AC amplitude of Vcom during Vcom AC drive. The amplitude can be specified within the range of 0.6 ~ 1.23 times of VREG1OUT. When VCOMG = 0, this setting is invalid. VCM4-0: Set the VcomH voltage (The higher voltage during Vcom AC drive). The voltage can be specified within the range of 0.4 ~ 0.98 times of VREG1OUT. When VCM4-0 = "11111", the internal volume adjustment operation is halted, and the VcomH voltage can be adjust by placing an external resistor from VcomR.

AD15-0: Make the initial setting of GRAM address in the address counter (AC). After GRAM data are written, the address counter is automatically updated according to the settings with AM, I/D bits and the setting for a new GRAM address is not required in the address counter. Therefore, data are written consecutively without resetting the address. The address counter is not automatically updated when data are read out from GRAM. GRAM address setting can not be made during the standby mode. An address set should be made within the area specified with the window address. When the RGB interface is selected (RM = 1), the setting of the address for AD15-0 is made every frame at the falling edge of VSYNC. When the internal clock operation or VSYNC interface is selected (RM = 0), the setting of the address is made when the instruction is executed.

WD17-0: All data are expanded into 18 bits internally before written to GRAM. Each interface has its own way of expanding data to 18 bits. The grayscale level is selected according to GRAM data. The address is automatically updated according to the setting with the AM and I/D bits after data are written to GRAM. During the standby mode, no access is allowed to GRAM. When 8 or 16 bit interface modes is selected, the data in the MSB of R and B pixels are also written to the LSB of R and B pixels respectively to expand the 8/16- bit data into the 18bit data internally. During the RGB interface mode, when writing data to RAM through a system interface, make sure to avoid conflicts between writing through the RGB interface and writing through the system interface. When the 18-bit RGB interface is selected, the18-bit data in PD17-0 bits are written, and 262,144 colors are available. When the 16-bit RGB interface is selected, the data in the MSB of R and B pixels are also written to the LSB of R and B pixels respectively, and 65,536 colors are available.

HD66789 RAM Access through RGB-I/F and System I/F
Preliminary
The HD66789 writes all display data on the screens to the internal RAM. This enables the transfer of only the data for the moving picture area as well as for the frames for updating screens through the RGB interface. By writing data in the high speed write mode (HWM = 1) and with the window address function, the HD66789 enables a high-speed access to RAM with low power consumption while displaying moving pictures. In the frames other than the moving picture screen update, the display data in the area other than the moving picture area can be updated through a system interface. The RAM access is also possible through a system interface even in the RGB-I/F mode. In the RGB interface mode, data are written to RAM in synchronization with the DOTCLK during ENABLE = "Low". When writing data in the RGB-I/F mode through the system interface, it is necessary to set the ENABLE "High" to stop writing through the RGB interface. After accessing to RAM through the system interface, wait an enough time for the write/read bus cycle before starting accessing to RAM through the RGB interface. When RAM accesses through the RGB and system interfaces conflict, there will be no guarantee that data are properly written to RAM.

Note 1) When RGB-I/F is selected, the address setting is made at every falling edge of VSYNC. Note 2) The address set and the index set must be made before the RAM access throught the RGB interface. Note 3) The high-speed write mode should be used in RGB-I/F and VSYNC-I/F modes.

HD66789 Read Data Read from GRAM (R22h)
R/W R RS 1
Preliminary
RAM Read data (RD17-0) The pin assignment for DB17-0 varies for each interface (see below).
RD17-0: Read 18-bit data from GRAM. The bit assignment for the data that are read out from GRAM is different according to the interface. When data are read out from GRAM to the microcomputer, the first word read immediately after GRAM address set are latched in the internal read-data latch, and thereby the data in the data bus (DB17-0) are nullified. The second word is read as valid data. When the HD66789 performs an internal bit processing, such as logical operation, the data latched in the read-data latch are used to complete it by single read out operation. The data are expanded internally into 18 bits before going through the logical operation. When the 8-/16-bit interfaces are selected, GRAM data in the LSBs of R and B pixels are not read out. This function is not available in the RGB interface mode.

WM17-0: Write-mask the data when they are written to GRAM by bit. For example, if WM17 = 1, the WM17 write-mask the MSB of the data to write to GRAM so that the data in the MSB are not written to GRAM. The rest of WM16-0 bits also write-mask the data in the corresponding bits when these bits are set to "1". For details, see the "Graphics Operation Function" section. The WM17-0 bits write-mask the data to write to GRAM, which are expanded, if necessary, into 18 bits. This function is not available in the RGB-I/F mode.

Preliminary
Reset Function
The HD66789 makes internal initialization with RESET input. During RESET, the HD66789 is in a busy state, and no instruction from the MPU and access to GRAM are accepted. The time required for the RESET input is at least 1ms. In case of power-on reset, wait at least 10ms after the power is turned on until the R-C oscillation frequency becomes stabilized. While waiting, do not make an initial setting for the instruction set or an access to GRAM. Initial State of Instructions a. b. c. d. e. f. g. h. i. j. k. l. m. n. o. p. q.

Interface Specifications
The HD66789 incorporates a system interface to make settings for instructions, and an external display interface to display moving pictures. By selecting an optimum interface for display (moving or still picture, or both), data are transmitted efficiently. The external display interfaces are RGB-I/F and VSYNC-I/F. Through these interfaces, the data can be updated without flickering the moving picture on the display. In the RGB-I/F mode, the display operation is performed in synchronization with the signals (VSYNC, HSYNC, and DOTCLK). The display data are written according to the values of the data enable signal (ENABLE), data valid signal (VLD) and PD17-0 bits in synchronization with VSYNC, HSYNC, and DOTCLK signals. The display data are written to GRAM to reduce the data transmission to minimum, i.e. only when the displays are being updated. With the window address function, only the RAM area used for moving picture display is overwritten, and therefore the simultaneous display of moving picture area, which is overwritten, and the RAM data in the area other than the moving picture area, which is not overwritten, is possible. In the RGB and VSYNC interface modes, write data to GRAM in the high speed write mode (HWM = 1) while displaying moving pictures to make an access to GRAM in high speed with low power consumption. In the VSYNC interface mode, internal display operations are synchronized with the frame-synchronizing signal (VSYNC). By writing data in synchronization with the falling edge of VSYNC at a fixed speed to GRAM through a system interface, it enables moving pictures display with a system interface. In this case, there are some constraints in the RAM writing speed and method. The HD66789 handles the following 4 operational modes for the type of display. The setting can be made through an external display interface. A transition between the modes must follow the transition flow.

The 80-system 9-bit parallel data transmission becomes operable by setting IM3/2/1/0 pins to IOVcc/GND/IOVcc/IOVcc levels respectively. When transmitting a 16-bit instruction, it is divided into upper and lower 8 bits (the LSB is not used) and the upper 8 bits are transmitted first. The RAM data is also divided into the upper and lower 9 bits, and the upper bits are transmitted first. The unused pins DB8-0 must be fixed to either IOVcc or GND level. When writing into the index register, the upper byte (8 bits) must be written.

HD66789 Data transmission synchronizing in 9-bit bus interface mode
Preliminary
The HD66789 supports a data transmission synchronizing function, which resets the upper/lower counter that counts the number of transmission of upper/lower 9-bit data in the 9-bit bus interface mode. When a discrepancy occurs in the upper/lower 9-bit data transmission due to effects from noise and so on, the "00" H instruction is written 4 times consecutively to forcibly reset the upper/lower counter so that data transmission restarts with an upper 9-bit data transmission. The excursion can be recovered by executing the synchronizing function periodically.

HD66789 Serial Peripheral interface (SPI)
Preliminary
The Serial Peripheral Interface (SPI) becomes operable by setting IM3/2/1 pins to GND/IOVcc/GND levels respectively. The SPI is available through the chip select line (CS*), serial transfer clock line (SCL), serial data input (SDI), and serial data output (SDO). In the SPI mode, the IM0/ID pin functions as ID pin. In the SPI mode, the unused DB15-2 pins must be fixed at either IOVcc or GND level. The HD66789 recognizes the start of data transfer at the falling edge of CS* input to initiate the transfer of start byte. It recognizes the end of data transfer at the rising edge of CS* input. The HD66789 is selected when the 6-bit chip address in the start byte transferred from the transmission device and the 6-bit device identification code assigned to the HD66789 are compared and both 6-bit data correspond. When selected, the HD66789 starts taking in the subsequent data string. The setting for the least significant bit of the identification code is made with the ID pin. The five upper bits of the identification code must be 01110. Two different chip addresses must be assigned to the HD66789 because the seventh bit of the start byte is assigned to a register select bit (RS). When RS = 0, index register write or status read is executed. When RS = 1, instruction write or RAM read/write is executed. The eighth bit of the start byte is to specify read or write (R/W bit). The data are received when the R/W bit is 0, and are transmitted when the R/W bit is 1. In the SPI mode, the data are written to GRAM after two-byte data transmission. The data are expanded into 18 bits by adding one bit (the same data as the MSB of RB) next to the LSB of RB data. After receiving the start byte, the HD66789 starts to transmit or receive data by byte. The data transmission adopts a format by which the MSB is first transmitted. All HD66789 instructions consist of 16 bits and they are executed internally after two bytes are transmitted with the MSB first (DB15 to 0). The data to write to RAM are expanded into 18-bit data. After the start byte is received, the first byte is always fetched as the upper eight bits of the instruction and the second byte is fetched as the lower eight bits of the instruction. The 4-byte data that are read from RAM right after the start byte are made invalid. The HD66789 reads as valid data from the 5th-byte data. Start Byte Format

HD66789
Preliminary
VSYNC Interface
The HD66789 incorporates a VSYNC-I/F, which enables moving picture display with only a system interface and the frame-synchronizing signal (VSYNC). This interface enables moving picture display with minimum modification to a conventional system.
VSYNC HD66789 LCDC/ MPU CS* RS WR* 16 DB17-10, 8-1
VYSNC interface The VSYNC-I/F becomes operable by setting DM1-0 = 10 and RM = 0. In the VSYNC I/F mode, the internal display operations are synchronized with VSYNC. By writing data to RAM through a system interface in a speed that is higher for more than a fixed speed than the internal display operation speed, it enables moving picture display through a system interface, while preventing flickers while the screens are being updated. Display operations are executed by the internal clock generated by the internal oscillator and VSYNC input. All display data are stored in RAM. This enables moving picture display only by transmitting data that are written over, thereby minimizing the number of data transmission while displaying moving picture. The high-speed write mode (HWM = 1) enables RAM access in high speed with low power consumption.

Moving picture data transmission through VSYNC interface
Rev.0.12, May 09 2003, page 84 of 156
HD66789
Preliminary
The VSYNC-I/F has limits on the minimum speed for RAM write through a system interface and the frequency of the internal clock. It requires RAM write speed more than the result that is calculated from the following formula.
* * Internal clock frequency (fosc) [Hz] = Frame frequency x (Display line (NL) + Front porch (FP) + Back porch (BP)) x 16 clocks x Fluctuation Minimum speed for RAM write (min.)[Hz] > 176 x Display line (NL) / {((Back porch (BP) + Display raster-row (NL) - Margin) x 16 clocks) / fosc}
Note 1) When RAM write does not start right after the falling edge of VSYNC, the time between the falling edge of VSYNC and the start of RAM write must also be taken into account.
An example of the RAM write speed and the frequency of the internal clock in the VSYNC interface mode is as follows. [Example] Display size Display line Back/front porch Frame frequency 176 RGB x 240 lines 240 lines (NL = 11110) 14/2 lines (BP = 1110/FP = 0010) 60 Hz
Internal clock frequency (fosc) [Hz] = 60 Hz x (240 + 2 + 14) x 16 Clock x 1.1 / 0.9 = 300 kHz When calculating the internal clock frequency, possible causes of fluctuations must also be taken into consideration. The allowance for this fluctuation is 10 % from the center value, and the range of the frequency must be within VSYNC period. As the causes of fluctuations, the above example takes the variation in the LSI fabrication and the room temperature into account. Other possible causes of fluctuations, such as variation in the external resistors or the voltage change are not considered in the above example. It is necessary to make a setting with enough margins to include the allowances for these factors. Minimum speed for RAM writing [Hz] > 176 x 240 / {((14 + 240 - 2) raster-rows x 16 clock) / 300 kHz} = 3.14 MHz In this case, RAM write is performed in synchronization with the falling edge of VSYNC. When the data for one frame are written to RAM completely, there must be more than 2 raster-rows of margin before the raster-rows driven for the display. By writing data to RAM on the falling edge of VSYNC at the speed of 3.14 MHz or more, the data for the whole screen on RAM are overwritten before the display operation starts. Accordingly, the flicker due to updating moving picture data can be avoided while displaying a moving picture.

The aforementioned example of calculation is the value in case of writing over the entire screen. Limiting the area for the moving picture display will create more margins for the RAM write speed.

HD66789 Moving picture display
Preliminary
The HD66789 incorporates the RGB interface to display moving pictures and RAM to store display data, which provides the following merits in displaying moving pictures. * * * * * The window address function enables the transfer of only data for the moving picture area. The high-speed write mode enables high-speed access to RAM with low power consumption Only transmitting data that are written over the moving picture area. Reduced transmission contributes to the reduction of power consumption of the entire system. In combination with a system interface, the still picture area, such as an icon, can be updated while displaying moving pictures.
RAM access through system interface in RGB-I/F mode RAM is accessible through a system interface in the RGB-I/F mode. In the RGB interface mode, data are being written to RAM in synchronization with the DOTCLK input while the ENABLE is "Low". When writing data to RAM through the system interface, it is necessary to set ENABLE to "High" to stop data write through the RGB-I/F. Setting RM = 0 allows RAM access through the system interface. When reverting to the RGB interface mode, wait a write/read bus cycle. Then, set RM = 1 and the index to R22h to start RAM access though the RGB-I/F. When the RAM writes through the RGB and system interface conflicts, it is not guaranteed that the data are properly written to RAM. The following is an example of moving picture display through the RGB-I/F and updating still picture area through the system interface.

Data format for 6-bit interface Data transmission synchronization in 6-bit RGB interface mode The HD66789 incorporates a transmission counter to count the first, second, third data transmissions in the 6-bit RBG interface mode. The transmission counter is reset to the first transmission on the falling edge of VSYNC. When a discrepancy occurs in the transmission of first, second and third data, the counter is reset so that a first data transmission will be made at the start of each frame (on the falling edge of VSYNC) and the data transmission restarts in the correct order from the next frame. In case of displaying moving pictures, which requires consecutive data transfer, this function minimizes the effect from the discrepancy in the data transmission and makes it easy to return to the normal display. The internal display operation is executed by pixel. Note that each DOTCLK input must correspond to a pixel. Otherwise data transmission discrepancies will occur and affect the displays of the current and ensuing frames.

The VSYNC, HSYNC, and DOTCLK signals must be supplied consecutively during display operation through the RGB-I/F. When setting NO1-0, SDT1-0, and EQ1-0 bits in the RGB-I/F mode, the reference clock is the DOTCLK, not the internal operation clock. In the 6-bit RGB-I/F mode, RGB (pixels) data are transmitted by three clocks. The data transmission, therefore, should be made by RGB. In the 6-bit RGB-I/F mode, the interface signals, VSYNC, HSYNC, DOTCL, ENABLE, VLD, and PD17-0, should be set by RGB (pixels) in convenience for transmitting RGB pixels. The transitions between the internal operation mode and external display interface should be made according to the mode switching sequence below. In the RGB-I/F mode, the front porch period continues after displaying one frame data until the next VSYNC signal input. In the RGB-I/F mode, the data must be written in the high-speed write mode (HWM = 1). In the RGB-I/F mode, the address is set every frame on the falling edge of VSYNC.

HD66789
Preliminary
High-Speed Burst RAM Write Function
The HD66789 incorporates high-speed burst RAM-write function, which writes data to RAM in one-fourth the access time required for a standard RAM-write operation. This function is especially useful for applications which require the high-speed rewrite of the display data such as display of colored moving picture and so on. In the high-speed RAM write mode (HWM), data to write to RAM is temporarily stored to the internal register of HD66789. The data storage in the register is executed by word. When the data storage operation is executed 4 times, all data stored in the register are written to RAM at once. While the data is being written from the register to RAM, another set of data is being written to the register. This function enables high-speed and consecutive RAM write, which are required in displaying moving pictures and so on.

"The lower two bits of the address must be set as follows in high-speed write mode. When ID0 = 0, set the lower two bits of the address to 11. When ID1 = 1, set the lower two bits of the address to 00. Note : In the high-speed mode (HWM), data are written to the RAM every 4 words. This means in the 8-bit interface mode, data are written to the RAM for every eight write operation.

The RAM write operation is executed every four words. Set the lower 2 bits of the addresses as follows when setting the address. *When ID0=0, the lower two bits in the address must be set to 11 before RAM write. *When ID0=1, the lower two bits in the address must be set to 00 before RAM write. 3. The RAM write operation is executed every four words. If the RAM write operation is terminated before all four-word data is written to RAM, the last data will not be written to RAM. When the index register is set to R22H (RAM data write), the first RAM write operation is always executed. In this case, the RAM data read is not operable simultaneously. During RAM read, set the HWM to 0. The high-speed RAM write mode is not compatible with the normal RAM write mode. When the mode must be switched to the other, make a new address set before starting RAM write. When writing data in the high speed RAM write mode within the range specified with the window address, some window-address range may require dummy write operation. See "High-Speed RAM Write with Window Address Function".

HD66789 High-Speed RAM Write with Window Address
Preliminary
To rewrite the data in an arbitrary rectangular area of RAM consecutively in high speed, the number of RAM access should be made 4 multiple times. Accordingly some window-address range may require dummy write operation to make the RAM access 4 multiple times. The number of dummy write is set when setting the window address as follows. The horizontal window-address range specifying bits (HSA1-0, HEA1-0) specify the number of dummy write operations executed at the start and end of the data to write to RAM. The total RAM access must be 4 multiple times per line. Number of Dummy Write Operations in High-Speed RAM Write (HSA Bits)
HSA1 0 0 1 1 HSA0 0 1 0 1 Number of Dummy Write Operations inserted 0 1 2 3
Number of Dummy Write Operations in High-Speed RAM Write (HEA Bits)
HEA1 0 0 1 1 HEA0 0 1 0 1 Number of Dummy Write Operations inserted 3 2 1 0
The number of RAM access when writing data in the horizontal direction must be made 4 x N times by including the dummy writes. Horizontal RAM write = start dummy write + write data + end dummy write = 4 x N (times) An example of RAM write in high speed RAM write mode with the window address is as follows. The RAM data in the specified window-address range is written over consecutively in high speed by inserting two dummy writes at the start of the line and three dummy writes at the end of the line. The number of dummy writes is specified with the window-address range specifying bits. In this case, set HSA1-0 to 10, HEA1-0 to 00.

HD66789
Preliminary
Window Address Function
The window address function enables consecutive data write within the rectangular window-address area on the on-chip GRAM, which is specified with horizontal address registers (start: HSA7-0, end: HEA 7-0) and vertical address registers (start: VSA7-0, end: VEA7-0). The address transition direction is determined with AM bits (either increment or decrement). Accordingly, the data, including picture data, are written consecutively without taking the data wrap position into consideration. The window-address range must be specified within the GRAM address area. An address set must be set within the window-address range. [Condition on setting window-address range] (horizontal direction) 00H HSA7-0 HSA7-0 AFH (vertical direction) 00H VSA7-0 VEA7-0 EFH [Condition on making an address set within the window-address range] (RAM address) HSA7-0 AD7 -0 HEA7-0 VSA7-0 AD15-8 VEA7-0 Note: In high-speed RAM write mode , the lower two bits of the address must be set as follows. ID0=0: The lower two bits of the address must be set to 11. ID0=1: The lower two bits of the address must be set to 00.

Graphics Operation Function
The HD66789 greatly reduces the load on the graphics-processing software in the microcomputer with the 18-bit bus architecture and the graphics bit operation. The graphics bit operation includes: 1. The write data mask function that selectively rewrites some of the 18-bit write data. 2. The conditional rewrite function that compares the write data and the compare bit data and writes the data sent from the microcomputer only when the conditions are satisfied. The graphics bit operation is controlled by setting bits in the entry mode register and RAM-write-data mask register, and the write operation from the microcomputer. Graphics Operation

HD66789 Write-data Mask Function
Preliminary
The HD66789 expands the 16-bit data sent from the microcomputer into the 18-bit data. In the18-bit interface mode, data are not expanded. The write data mask function of the HD66789 controls the write operation of the 18-bit data from the microcomputer to GRAM by bit. The write data mask function write data in the bits whose corresponding bits in the write data mask resister (WM17-0) are assigned with "0". It does not write data in the bits whose corresponding bits in the write data mask register (WM17-0) are assigned with "1", and the corresponding data in GRAM are not overwritten but retained. This function is useful when only one-pixel data are rewritten or a particular color in the display is selectively changed.

Write data mask function Graphics Operation Processing 1. Write mode 1: AM = 0, LG2-0 = 000 This mode is used when data are horizontally written in high-speed mode. It is also used to initialize the graphics RAM (GRAM) or to draw a line horizontally. The write-data mask function (WM17-0) is also available with this mode. After writing, the address counter (AC) automatically increments by 1 (I/D = 1) or decrements by 1 (I/D = 0), and jumps to the counter at the opposing edge of the next one-raster-row below after when the counter reaches either left or right edge of GRAM.

This mode is used when data are vertically written in high-speed mode. It is also used to initialize the graphics RAM (GRAM), develop font patterns or draw a line vertically. The write-data mask function (WM17-0) is also available with this mode. After writing, the address counter (AC) automatically increments by 256, and automatically jumps to the counter either at the top of the next right row (ID = 1) or at the top of the next left row (I/D = 0) according to the setting in the I/D bit, when the address reaches the bottom of GRAM.

HD66789 -Correction Register
Preliminary
The -adjustment register is a group of registers to set an appropriate grayscale voltage for the characteristics of a liquid crystal panel. The register group is categorized into the ones adjusting gradient, amplitude, and fine-tuning in relation to grayscale number and grayscale voltage characteristics. Each register can make an independent setting for the positive/negative polarity. The reference value and RGB are common to both polarities.

Gradient, Amplitude, Fine Adjustments 1. Gradient adjustment registers The gradient adjustment registers are used to adjust the gradient around the middle of the grayscale number and voltage characteristics without changing a dynamic range. To adjust a gradient, the values of the variable resistors (VRHP (N)/VRLP (N)) in the middle of the ladder resistor block for grayscale voltage generation are controlled. The registers incorporate separate registers for positive and negative polarities to be compatible with asymmetric drive. 2. Amplitude adjustment registers The amplitude adjustment registers are used to adjust the amplitude of the grayscale voltage. To adjust the amplitude, the values of the variable resistors (VRP(N)1/0) in the bottom of the ladder resistor block for grayscale voltage generation are adjusted. Same with the gradient registers, the amplitude adjustment registers also incorporate separate registers for positive and negative polarities. 3. Fine adjustment registers The fine adjustment register is to fine-adjust the grayscale voltage level. To fine-adjust the grayscale voltage level, each level of 8-level reference voltages generated from the ladder registers is controlled by 8to-1 selector. Same with the other registers, the fine-adjustment registers also incorporate separate registers for positive and negative polarities.

Ladder resistors and 8-to-1 selector Block configuration The block diagram of page 112 consists of two ladder resistors including variable resistors, and 8-to-1 selectors which select the voltage generated by the ladder resistors to output a reference voltage for the grayscale voltage. The variable resistors and the 8-to-1 selectors are controlled by the correction registers. Pins that are connected to a variable resistor are provided to compensate the variation among the panels. Variable resistor There are three kinds of variable resistors for the gradient adjustment (VRHP(N)/VRLP(N)), the amplitude adjustment (1) (VRP(N)0), and the amplitude adjustment (2) (VRP(N)1). The resistance is determined by the gradient adjustment and amplitude adjustment registers as is shown below. Gradient adjustment

8-color Display Mode
The HD66789 incorporates 8-color display mode. The available grayscale levels are V0 and V31, and the voltages for the other levels (V1-V30) are halted to reduce power consumption. The -fine-adjustment registers, PKP0-PKP5 and PKN0-PKN5 are not available in the 8-color display mode. Since the power supply for the levels V1-V30 are halted, RGB data in GRAM should be set to either "000000" or "111111" before setting this mode so that V0 or V31 is selected.

Oscillation Circuit
The HD66789 generates oscillation by internal R-C oscillator with an external oscillation resistor placed between the OSC1 and OSC2 pins. The oscillation frequency varies depending on the value of external resistor, the distance of wiring, and the power supply voltage for the oscillation. For example, the oscillation frequency becomes low when increasing the value of Rf resistor, or lowering the power supply voltage. See the "Electric Characteristics Notes" section for the relationship between the Rf resistor value and the oscillation frequency.

Note 1) Place the Rf resistor as close as to the OSC1, OSC2 pins. Note 2) Make sure not to arrange other wiring beneath or close to OSC1-OSC2 wiring to avoid effects from coupling.

n-raster-row Inversion AC Drive
The HD66789, in addition to LCD inversion AC drive by frame, supports n-raster-row inversion AC drive where alternation occurs by n raster-rows, where n takes a number between 1 to 64. The n-raster-row inversion AC drive enables to overcome the problems related to display quality. In determining n (the value set in the NW bit +1), the number of raster-rows by which alternation occurs, check the display quality on the actual liquid crystal panel. Setting a small number of raster-rows will raise the AC frequency of the liquid crystal and increase the charge/discharge current on the liquid crystal cells..

Interlaced Drive
The HD66789 supports interlaced drive, which divides one frame into n fields and then drives to prevent flickers. To determine the number of fields (n: value set in the FLD bits), check the display quality on the actual liquid crystal panel. The following table shows the gate selection for each number of fields, 1 to 3. The figure illustrates the output waveforms of the 3-field interlaced drive. Gate selection

AC Timing
The AC timings of frame inversion AC drive, 3-field interlaced drive, and n-raster-row inversion drive are illustrated as follows. In case of frame inversion AC drive, alternation occurs at the completion of drawing one frame, followed by a blank, which lasts for 16H periods. In this case, all outputs from the gate are Vgoff outputs. In case of interlaced drive, alternation occurs at the completion of drawing one field, followed by a blank. The total period of the blanks in one frame amounts to 16H period. In case of nraster-row, a blank lasting 16H period is inserted after drawing a full screen. During interlaced drive, make the numbers of back and front porches more than that of field.

Frame-Frequency Adjustment Function
The HD66789 incorporates frame frequency adjustment function. The frame frequency during the liquid crystal drive is adjusted by the instruction setting (DIV, RTN) while keeping the oscillation frequency fixed. Setting the oscillation frequency high in advance allows switching the frame frequency in accordance to the kind of displayed picture (i.e. moving/still picture). When displaying a still picture, set the frame frequency low to save power consumption, while setting the frame frequency high when displaying a moving picture which requires high-speed switching of screens. Relationship between Liquid Crystal Drive Duty and Frame Frequency The relationship between the liquid crystal drive duty and the frame frequency is calculated by the following formula. The frame frequency is adjusted through the instruction setting with the 1-H period adjustment bit (RTN bit) and the operation clock division bit (DIV bit). (Formula for the frame frequency) fosc Frame frequency = Clock cycles per raster-row x division ratio x (Line+BP+FP) fosc: R-C oscillation frequency Line: number of drive raster-rows (NL bit) Clock cycles per raster-row: RTN bit Division ratio: DIV bit The number of raster-rows for the front porch: FP The number of raster-rows for the back porch: BP [Hz]
Calculation Example
The maximum frame frequency = 60 Hz
Number of drive raster-rows: 240 1-H period: 16 clock cycles (RTN3-0 = 0000) Operation clock division ratio: 1 division fosc = 60 Hz x (0 + 16) clock x 1 division x (240 + 16) lines = 246 (kHz) In this case, the R-C oscillation frequency becomes 246 kHz. Adjust the external resistor to the R-C oscillator to 246 kHz.

Screen -split Drive Function
The HD66789 allows selectively driving two screens at arbitrary positions with the screen-drive position registers (R42 and R43). Only the raster-rows required to display two screens at arbitrary positions are selectively driven to reduce power consumption. The first screen drive position register (R42) specifies the start line (SS17-10) and the end line (SE17-10) for displaying the first screen. The second screen drive position register (R43) specifies the start line (SS27-20) and the end line (SE27-20) for displaying the second screen. The second screen control is effective when the SPT bit is set to 1. The total number of raster-rows driven for displaying the first and second screens must be less than the number of liquid crystal drive raster-rows.

This excludes the current flowing through output drive MOSs. This excludes the current flowing through the input/output units. The input level must be fixed high or low because through current increases if the CMOS input is left floating. Even if the CS pin is low or high when an access with the interface pin is not performed, current consumption does not change. The following figure shows the relationship between the operation frequency and current consumption.
