Hi,

is P1 5V tolerant?

Datasheet hardware description: P3/P4

Datasheet AC/DC-Parameters: P1/P3/P4

What is correctly.

port 3 and 4 are 5V tolerant.

Port 1 is not 5V tolerant bcoz it is shared with ADC.

Port A,B,C,D of PSD module are 3.3V tolerant.

The pins on Port 4 have a higher current capability than the pins on Ports 1

and 3.
