Description

Legend:

AN = Analog input or output

CMOS = CMOS compatible input or output

OD = Open-Drain

TTL = TTL compatible input

ST = Schmitt Trigger input with CMOS levels

I2C = Schmitt Trigger input with I2C

Note 1: The Analog/Digital Debug Output is selected through the control of the ABECON register.

Selected when functioning as master or slave by proper configuration of the MSC<1:0> bits in the MODECON register.

VREF2 output selected when configured as master by proper configuration of the MSC<1:0> bits in the MODECON
