PORTJ is an 8-bit wide, bi-directional I/O port. The cor-
responding data direction register is TRISJ. Setting a
TRISJ bit (= 1) will make the corresponding PORTJ pin
an input (i.e., put the corresponding output driver in a
Hi-Impedance mode). Clearing a TRISJ bit (= 0) will
make the corresponding PORTJ pin an output (i.e., put
the contents of the output latch on the selected pin).
Read-modify-write operations on the LATJ register
read and write the latched output value for PORTJ.
PORTJ is multiplexed with de-multiplexed system data
bus D7:D0, when device is configured in 8-bit execution
mode. Register MEMCON configures PORTJ as I/O or
system bus pins.

PORTJ is available only on PIC18C801
devices.
On Power-on Reset, PORTJ defaults to
system bus signals.
