PIC18F87J10 FAMILY
11.7
PORTF is a 7-bit wide, bidirectional port. The corre-
sponding Data Direction register is TRISF. Setting a
TRISF bit (= 1) will make the corresponding PORTF pin
an input (i.e., put the corresponding output driver in a
high-impedance mode). Clearing a TRISF bit (= 0) will
make the corresponding PORTF pin an output (i.e., put
the contents of the output latch on the selected pin).
Only pin 7 of PORTF has no analog input; it is the only
pin that can tolerate voltages up to 5.5V.
The Output Latch register (LATF) is also memory
mapped. Read-modify-write operations on the LATF
register read and write the latched output value for
PORTF.
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 several analog peripheral
functions, including the A/D Converter and comparator
inputs, as well as the comparator outputs. Pins, RF2
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.
