Data is directed to this module based upon the input of the D/C# pin. If D/C# is high, data is written to Graphic Display Data RAM (GDDRAM). If D/C# is low, the input at D0 -D7 is interpreted as a command and it will be decoded and written to the corresponding command register. Reset is of the same function as Power ON Reset (POR). Once RES# receives a negative reset pulse of about 1us, all internal circuitry will be back to its initial status. Refer to Command Description section for more information. www..com 7.2 MPU Parallel 6800-series Interface The parallel interface consists of 8 bi-directional data pins (D0 - D7), R/W(WR#), D/C#, E(RD#) and CS#. R/W(WR#) input High indicates a read operation from the Graphic Display Data RAM (GDDRAM) or the status register. R/W(WR#) input Low indicates a write operation to Display Data RAM or Internal Command Registers depending on the status of RS input. The E(RD#) and CS# input serves as data latch signal (clock) when they are high and low respectively. Refer to Figure 14 of parallel timing characteristics for Parallel Interface Timing Diagram of 6800-series microprocessors. In order to match the operating frequency of display RAM with that of the microprocessor, some pipeline processing is internally performed which requires the insertion of a dummy read before the first actual display data read. This is shown in Figure 3 below. R/W(WR) E(RD) data bus N writ e column address dummy read n data read1 n+1 data read 2 n+2 data read 3 Figure 3 - Display Data Read with the insertion of Dummy Read 7.3 MPU Parallel 8080-series Interface The parallel interface consists of 8 bi-directional data pins (D0 - D7), R/W(WR#), E(RD#), D/C# and CS#. The CS# input serves as data latch signal (clock) when it is low. Whether it is display data or status register read is controlled by D/C#. R/W(WR#) and E(RD#) input indicates a write or read cycle when CS# is low. Refer to Figure 16 of parallel timing characteristics for Parallel Interface Timing Diagram of 8080-series microprocessor. Similar to 6800-series interface, a dummy read is also required before the first actual display data read. SSD1858 Rev 1.1 09/2002 SOLOMON 12 7.4 MPU Serial 4-wire Interface The serial interface consists of serial clock SCK, serial data SDA, D/C# and CS#. SDA is shifted into an 8-bit shift register on every rising edge of SCL in the order of D7, D6, ... D0. D/C# is sampled on every eighth clock and the data byte in the shift register is written to the Display Data RAM or command register in the same clock. No extra clock or command is required to end the transmission. 7.5 MPU Serial 3-wire interface Operation is similar to 4-wire serial interface while D/C# is not been used. The Display Data Length instruction is used to indicate that a specified number display data byte(s) (1-256) are to be transmitted. Next byte after the display data string is handled as a command. It should be noted that if there is a signal glitch at SCK that causing an out of synchronization in the serial communication, a hardware reset pulse at RES# pin is required to initialize the chip for re-synchronization. www..com Table 6 -Modes of Operation 6800 Parallel Data Read Data Write Yes Yes 8080 Parallel Yes Yes Status only Yes No Yes No Yes Serial Command Read Status only Command Write Yes 7.6 Graphic Display Data RAM (GDDRAM) The GDDRAM is a bit mapped static RAM holding the bit pattern to be displayed. The size of the RAM is 104 x 65 x 2 = 13,520bits. Figure 5 is a description of the GDDRAM address map. For mechanical flexibility, re-mapping on both Segment and Common outputs are provided. For vertical scrolling of display, an internal register storing the display start line can be set to control the portion of the RAM data mapped to the display. Figure 5 shows the case in which the display start line register is set at 30H. For those GDDRAM out of the display common range, they could still be accessed, for either preparation of vertical scrolling data or even for the system usage. 7.7 Oscillator Circuit This module is an On-Chip low power RC oscillator circuitry (Figure 4). The oscillator generates the clock for the DC-DC voltage converter. This clock is also used in the Display Timing Generator. Oscillator enable enable Oscillation Circuit enable Buffer (CL) Internal Resistor OSC1 OSC2 Figure 4 - Oscillator Circuitry 13 SSD1858 Rev 1.1 09/2002 SOLOMON 7.8 LCD Driving Voltage Generator and Regulator This module generates the LCD voltage needed for display output. It takes a single supply input and generates necessary bias voltages. It consists of: 1. 2X, 3X, 4X and 5X DC-DC voltage converter 2. Bias Divider If the output op-amp buffer option in Set Power Control Register command is enabled, this circuit block will divide the regulator output (Vout) to give the LCD driving levels (VL2 - VL5). The divider does not require external capacitors to reduce the external hardware and pin counts. 3. Contrast Control www..com Software control of 64 voltage levels of LCD voltage. 4. Bias Ratio Selection circuitry Software control of 1/4 to 1/9 bias ratio to match the characteristic of LCD panel. 5. Self adjust temperature compensation circuitry Provide 5 different compensation grade selections to satisfy the various liquid crystal temperature grades. The grading can be selected by software control. Defaulted temperature coefficient (TC) value is -0.14%/C. 7.9 169 Bit Latch A register carries the display signal information. In 104 X 65 display-mode, data will be fed to the HV-buffer Cell and level-shifted to the required level. 7.10 Level selector Level Selector is a control of the display synchronization. Display voltage can be separated into two sets and used with different cycles. Synchronization is important since it selects the required LCD voltage level to the HV Buffer Cell, which in turn outputs the COM or SEG LCD waveform. 7.11 HV Buffer Cell (Level Shifter) HV Buffer Cell works as a level shifter, which translated the low voltage output signal to the required driving voltage. The output is shifted out with an internal FRM clock, which comes from the Display Timing Generator. The voltage levels are given by the level selector, which is synchronized with the internal M signal.
