corresponding Data Direction and Output Latch registers
PIC18F87K90 FAMILY
11.10 PORTJ, TRISJ and
PORTJ is an 8-bit wide, bidirectional port. The
are TRISJ and LATJ.
All pins on PORTJ are implemented with Schmitt
Trigger input buffers. Each pin is individually
configurable as an input or output.
All PORTJ pins, except RJ0, are multiplexed with LCD
segment drives controlled by the LCDSE4 register. I/O
port functions are only available on these pins when the
segments are disabled.

Note:
Note:
LATJ Registers
PORTJ is available only on 80-pin devices.
These pins are configured as digital inputs
on any device Reset.
Each of the PORTJ pins has a weak internal pull-up. A
single control bit can turn off all the pull-ups. This is
performed by clearing bit RJPU (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.
