Could you please clarify electrical specification of the PD/AD pin(22pin)?
There is no description about PD/AD pin on Datasheet electrical specification Table 1. DIGITAL INPUT.
Datasheet ablolute maximum rating says the PD pin is 5V torelant(-0.3V to +5.5V).
Hardware User Guide advices to connect it to GND or AVDD(1.8V).
Can it be connected to DVDD_3V as well?
