PORTF is an 8-bit wide, bidirectional port. The
corresponding Data Direction and Output Latch registers
are TRISF and LATF. All pins on PORTF are
implemented with Schmitt Trigger input buffers. Each pin
is individually configurable as an input or output.
Each of the PORTF pins has a weak internal pull-up. A
single control bit can turn off all the pull-ups. This is
done by clearing bit, RFPU (PADCFG1<5>). The weak
pull-up is automatically turned off when the port pin is
configured as an output. The pull-ups are disabled on
any device Reset.
