TABLE 12-16: SUMMARY OF REGISTERS ASSOCIATED WITH PORTH
12.10 PORTJ, TRISJ and
PORTJ is an 8-bit wide, bidirectional port. The
corresponding Data Direction and Output Latch registers
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.
When the external memory interface is enabled, all of
the PORTJ pins function as control outputs for the inter-
face. This occurs automatically when the interface is
enabled
(MEMCON<7>). The TRISJ bits are also overridden.

PORTJ is available only on 80-pin devices.
Unimplemented on 64-pin devices (PIC18F6XK22), read as ‘0’.
Unimplemented on PIC18FX5K22 devices, read as ‘0’.
These pins are configured as digital inputs
on any device Reset.

PIC18F87K22 FAMILY
Each of the PORTJ pins has a weak internal pull-up.
The pull-ups are provided to keep the inputs at a known
state for the external memory interface while powering
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.
