Pin	Signal	Direction	Function
1	VCC Supply input	Supply input	Primary device supply. Place the bypass capacitor close to this pin.
2	ADDR Input	Input	Low selects 0x23. High selects 0x5C. Do not leave this terminal floating.
3	GND Supply return	Supply return	Connect to the common ground plane or bench return.
4	SDA Bidirectional	Bidirectional	Open-drain I²C data. The bus needs a pull-up to its logic rail.
5	DVI Reference input	Reference input	I²C reference and active-low asynchronous reset. Hold at or below 0.4 V for at least 1 µs after VCC is supplied.
6	SCL Input	Input	I²C clock. Connect to the host clock line with its bus pull-up.
7	Exposed pad Leave open	Leave open	Do not solder or electrically connect the exposed underside pad.

Select 0x23 or 0x5C using ADDR. Send one command per write transaction. Read the result as two bytes, most significant byte first.
