For a serial peripheral interface(SPI), input data is fetched at the
I rising edge of the SCL signal, Fix SDI pin at VSS level if the pin
is not used.
For a serial peripheral interface (SPI), serves as the serial data
O olutput pin(SDO), Successive bits are output at the falling edge
of the SCL signal.
Chip select signal input pin.
I 0= driver IC is selected and can be accessed.
1= driver IC is not selected and cannot be accessed.

Reset pin initializes the IC when low. Should be reset after
power-on.
O
Internal power for RAM. Connect a capacitance to gnd. Connect a
capacitance(1u/10v) to gnd.
O
A reference level for the grayscale voltage. Connect a
capacitance(1u/10v) to gnd.
I Power supply for analog circuit(2.5v~3.3v)
O
The positive voltage used in the gate driver. Connect a
capacitance(1u/10v) to gnd.
O
The negative voltage used in the gate driver. Connect a
capacitance(1u/10v) to gnd.
Ground
