PORTJ is an 8-bit wide, bidirectional port. The corre-
sponding 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
high-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).
The Data Latch register (LATJ) is also memory
mapped. Read-modify-write operations on the LATJ
register, read and write the latched output value for
PORTJ.
PORTJ is multiplexed with the system bus as the exter-
nal memory interface; I/O port functions are only avail-
able when the system bus is disabled. When operating
as the external memory interface, PORTJ provides the
control signal to external memory devices. The RJ5 pin
is not multiplexed with any system bus functions.
When enabling peripheral functions, care should be
taken in defining TRIS bits for each PORTJ pin. Some
peripherals override the TRIS bit to make a pin an
output, while other peripherals override the TRIS bit to
make a pin an input. The user should refer to the corre-
sponding peripheral section for the correct TRIS bit
settings.
The pin override value is not loaded into the TRIS reg-
ister. This allows read-modify-write of the TRIS register,
without concern due to peripheral overrides.
