PIC18F97J60 FAMILY

PORTF is implemented as a bidirectional port in two
different ways:
• 64-pin and 80-pin devices: 7 bits wide (RF<7:1>)
• 100-pin devices: 8 bits wide (RF<7:0>)
The corresponding 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 RF1
through RF6 may be used as comparator inputs or
outputs by setting the appropriate bits in the CMCON
register. To use RF6:RF1 as digital inputs, it is also
necessary to turn off the comparators.
