SNL310 16-bit lcd controller 4. i/o port SNL310 provides totally 64 i/o pins (p2.0~ p2.15, p3.0~p3.15, p4.0~p4.15, and p5.0~p5.15). the input pull high resistor of each pin can be programmed by port pull-high register and the dire ction of i/o port is selected by port direction register. the port2 (p2.0~p2.15) and port 3 (p3.0~p3.15) can wake t he chip up from the stop mode and watch mode. these 64 programmable i/o pins provides not only a simply input/output function but also flexible configuration. it can be conf igured to be an 8-bit microprocessor interface to drive external devices, such as mask rom, flash and sram and lcd driver. furthermore, the pins ?txd? and ?rxd? are shared with p3.0 and p3.1. the internal structure of i/o pins is showed in figure-2 . pull-up resister latch pad to internal bus pull-up select in/out control in/out control i/o configuration of port2 ~ port5 figure-2 in some applications (e.g., infra red, ir), an output port needs to be modulated a carry signal. in the cases, the routine of modulat ion will occupy too many cpu computations. thus, a modulation circuit is built in chip to reduce cpu?s loading, timer2 overflow p3.3 2 iren i/o pad figure-3 ver: 1.7 m ay 2, 2003 5
SNL310 16-bit lcd controller the modulation function will be active when t he control bit ?iren? set to ?1?. and setting timer2 can generate the frequency of carry signal. 5. timer/counter SNL310 provides three 8-bit timer/event c ounters (t0/t1/t2). each timer is 8-bit binary up-count timer with pre-scalar and aut o-reload function. timer 0 (t0) was used when voice playing, so user should avoid to use t0.

SNL310 16-bit lcd controller the addressing capacity of each external device is showed in table-2 . the memory allocation of each bank is 64k words and t he addressing region of each device totally includes 64 banks except 1 st device. in fact, the ram bank of 1 st device is shared with internal memory of SNL310, so there are only 56 banks in the first device. in another hand, user can not use full memory location in the first device. the actual addressing capacity of first device is less than 64m bits (64m bits ? 8m bits) = 56m bits in 16-bit mode. user's data or program 32m bit non-use 32m bits 0x0000000 0x03fffff 0x01fffff 64m bits 0x0200000 figure-7 user's data or program 8m bit non-use 56m bits 0x0000000 0x03fffff 0x0040000 0x003ffff 64m bits figure-8 ver: 1.7 m ay 2, 2003 10

SNL310 16-bit lcd controller 9. uart interface the built-in uart supports the serial data transmission. SNL310 provides data phase auto-clock calibration function. the rxd pin and txd pin are shared with p3.0 & p3.1, and user can switch p3.0 and p3.1 to be rxd and txd by configuring the rxd/txd enable bit of uartc register. user can configure the baud rate of uart from 1200bps to 115200bps just by using the singl e crystal system (16mhz crystal). all the clock base of baud rate is counting by timer2. 10. lcd driver interface 10.1 8-bit interface the extension bus of SNL310 s upports not only external memory device but also 8-bit 8080/6800 microprocessor interface for external lcd controller which already built-in lcd display ram. user should enable ext ension bus before driving external lcd driver, and define the chip select pin you used to connect to lcd driver in ebc register. in 8-bit interface lcd controller, lcd disp lay data is stored in lcd driver. any change of lcd display is sent out to external lcd driver?s ra m by addressing different sram space. the interface emulates the 8080/ 6800-series interface to speed up the interface data moving processing. figure-11 and figure-12 are the timing diagrams between SNL310 and lcd driver by using 8-bit 8080/6800 interface. ver: 1.7 m ay 2, 2003 13

SNL310 16-bit lcd controller 10.2 1-bit interface SNL310 supports not just 8-bit interface but al so 1-bit interface lcd driver. for this kind lcd driver doesn?t include display ram. a ll the display data is stored in host cpu. so host cpu has to specify a dedicate in terface to drive lcd driver. beside the interface, SNL310 reserves the last 2k words ram (0 x0800~0x0fff) for stored the display data, then interface circuit will send accurate signal to lcd driver automatically. p3.6~p3.10 can be configured to be 1-bit inte rface for lcd driver just by property setting control register. table-3 shows the relation between p3.6~p3.10 and lcd driver interface. i/o pin extension bus descriptions p3.6 lsd lcd serial data output p3.7 lco1 lcd serial mode clock out1 p3.8 lco2 lcd serial mode clock out2 p3.9 lfc lcd frame inversion control p3.10 coms com data synchronize signal table-3 10.3 lcd ram assignment generally, those 1-bit interfac e lcd drivers don?t built-in the lcd display ram. all the display data have been stored in cpu side. the SNL310 already built-in totally 4k words ram, so user can set a property value of lcd ram start address (lrsa) register to assign a ram location for l cd display data. the start address setting formula is shown as bellow: calculating formula of start address if seg number divided by 16 4096-(seg numbe/16)*com number => for b/w 4096-(seg numbe/16)*com number*2 => for 4 gray levels if seg number can?t divided by 16 4096-((seg numbe/16)+1)*com number => for b/w 4096-((seg numbe/16)+1)*com number*2 => for 4 gray levels once upon user set the start address of lcd display ram and active this interface function, chip will send the display data out to external lcd driver at the right time. ver: 1.7 m ay 2, 2003 16
