Note 1:

2:

O = Output, I = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Trigger Buffer Input,

I2C = I2Câ¢/SMBus Buffer Input, x = Donât care (TRIS bit does not affect port direction or is overridden for this option).

PSP is available only in Microcontroller mode.

This feature is available only on PIC18F8XK22 devices.
