PORTF is a 7-bit wide, bidirectional port. The

is individually configurable as an input or output.
PORTF is multiplexed with analog peripheral functions,
as well as LCD segments. Pins, RF1 through RF6, 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.

Note 1: On device Resets, pins, RF<6:1>, are
PORTF, LATF and TRISF Registers
2: To configure PORTF as digital I/O, turn off
configured as analog inputs and are read
as ‘0’.
the comparators and set the ADCON1
value.
PORTF is also multiplexed with LCD segment drives
controlled by bits in the LCDSE2 and LCDSE3
registers. I/O port functions are only available when the
segments are disabled.
