RESET

System reset pin. (RESX) signal is active low

SDA

When IM3: Low, SPI interface input/output pin. When IM3: High, SPI interface input pin. The data is latched on the rising edge of the SCL signal. If not used, please fix this pin at VDDI or DGND level.

DCX(SCL)

This pin is used to be serial interface clock. DCX=’1’: display data or parameter. DCX=’0’: command data. If not used, please fix this pin at VDDI or DGND.

CSX

Chip selection pin Low enable. High disable.
