Serial Interface (PS = "L")
Communication with the microprocessor occurs via a clock-synchronized serial peripheral interface when PS is low.
When using the serial interface, read operations are not allowed.
.
When the chip select inputs are valid(CS1B = “L”
& CS2 = “H”), the serial data is sent most significant bit first on the rising edge of a serial clock going into DB6 and
processed as 8-bit parallel data on the eighth clock. Since the clock signal is easy to be affected by the external
noise caused by the line length, the operation check on the actual machine is recommended. And not valid, the
internal 8-bit shift register and the 3-bit counter are reset.
The serial interface type is selected by setting C68 as shown in
Table 11
.

4-Pin SPI Interface (PS = "L", C68 = "H")
In 4-pin SPI 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.
