Pin No.	Symbol	Function
1	GND	Ground.
2	VCC	Power supply pin for core logic operation.
3	D0	The serial clock input
4	D1	The serial data input
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 pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the data at D1 will be interpreted as data. When the pin is pulled LOW, the data at D1 will be transferred to a command register. In I2C mode, this pin acts as SA0 for slave address selection.
7	CS#	This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW).
