Serial Interface (PS0 = "L")
When the S6B1741 is active(CSB="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 MCU by default. If messages on the data pin are data rather than
command, MCU 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.
