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 Invalid, the
internal shift register and the counter are reset.
The serial interface type is selected by setting PS as shown in Table12.

3-Pin SPI Interface (PS = "L" & MPU[1] = "L")
In 3-Pin SPI Interface mode, the pre-defined instruction called Display Data Length is used to indicate whether serial
data input is display or instruction data instead of D/I pin. The data is handled as instruction data until the Display
Data Length instruction is issued. This Display Data Length instruction consists of three bytes instruction. The first
byte instruction enables the next instruction to be valid, and data of the second two bytes indicate that a specified
number of display data bytes(1 to 65536) are to be transmitted. Next two bytes after the display data string is
handled as instruction data. For details, refer the Figure 8.
