Serial Interface (PS = "L")
When the S6B1400X is active (CS1B=” L”, CS2=” H”), 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 C68. When the RS pin
is used (PS = “ H” ), data is display data when RS is high, and command data when RS is low. When RS is not used
(C68 = “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 (10000000) 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 sending,
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.
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. Since the clock signal (DB6) is easy to be affected by the external noise caused by the line length,
the operation check on the actual machine is recommended.
The serial interface type is selected by setting C68 as shown in table 11.

4 Pin SPI Serial Interface (PS = "L", C68 = "H")
In 4-pin serial interface mode, RS pin is used for indicating whether serial data input is display or instruction data.
Data is display data when RS is high and instruction data when RS is low.
