I2CFIL = “L”: Fast Mode (400kHz)
I2CFIL = “H”: Fast Mode Plus (1MHz) (should be fixed to TVDD2)
Power-down Pin
I
Use this pin to power down the AK7735.
The PDN pin should be held “L” when power is supplied.
VREG Output Pin
O
Connect a 2.2uF(±30%) ceramic capacitor between this pin and
DVSS3. Do not connect this pin to an external circuit.
