PORTF is a 7-bit wide, bidirectional port. Only pin 7 of
PORTF has no analog input; it is the only pin that can
tolerate voltages up to 5.5V.
All pins on PORTF are implemented with Schmitt
Trigger input buffers. Each pin is individually
configurable as an input or output.
PORTF is multiplexed with analog peripheral functions.
RF1 through RF6 may also be used as analog input
channels for the A/D Converter. All pins may be used as
comparator inputs or outputs by setting the appropriate
bits in the CMCON register. To use RF<6:3> as digital
inputs, it is also necessary to turn off the comparators.
