81 COM / 128 SEG DRIVER & CONTROLLER FOR STN LCD

Serial Interface (PS0 = "L")
When the KS0759 is active(CS1B=”L”), serial data (DB7) and serial clock (DB6) inputs are enabled. And not
active, the internal 8-bit shift register and the 3-bit counter are reset. The display data/command indication may be
controlled either via software or the Register Select(RS) Pin, based on the setting of PS1. When the RS pin is
used (PS1 = “H”), data is display data when RS is high, and command data when RS is low. When RS is not used
(PS1 = “L”), the LCD Driver will receive command from MPU by default. If messages on the data pin are data
rather than command, MPU should send Data Direction command(11101000) to control the data direction and
then one more command to define the number of data bytes will be write. After these two continuous commands
are send, the following messages will be data rather than command. Serial data can be read on the rising edge of
serial clock going into DB6 and processed as 8-bit parallel data on the eighth serial clock. And the DDRAM
column address pointer will be increased by one automatically. The next bytes after the display data string is
handled as command data.
