Interface Pin Function

No. Symbol Function
1 GND Ground.
2 VCC Power supply pin for logic.
3 D0 When the serial interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SI).
4 D1
5 RES# This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) during normal operation.
6 D/C# This is the Data/Command control pad that determines whether the data bits are data or a command.
D/C = "H": the inputs at D0 and D1 are treated as display data.
D/C = "L": the inputs at D0 and D1 are transferred to the command registers.
7 CS# This pin is the chip select input. (active LOW)
