Interface Pin Function

No. Symbol Function
1 GND Ground
2 VCC Power supply input
3 D0 The serial clock input
4 D1 The serial data input
5 RES# This is a reset signal input pad. When RES# is set to "L", the settings are initialized. The reset operation is performed by the RES# signal level.
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 input at D1 is treated as display data
D/C# ="L":the input at D1 is transferred to the command registers.
7 CS# This pad is the chip select input. When CS# ="L", then the chip select becomes active, and data/command I/O is enabled.
