PIC18F87J10 FAMILY
11.8
PORTG is a 5-bit wide, bidirectional port. The corre-
sponding Data Direction register is TRISG. Setting a
TRISG bit (= 1) will make the corresponding PORTG
pin an input (i.e., put the corresponding output driver in
a high-impedance mode). Clearing a TRISG bit (= 0)
will make the corresponding PORTG pin an output (i.e.,
put the contents of the output latch on the selected pin).
All pins on PORTG are digital only and tolerate
voltages up to 5.5V.
The Output Latch register (LATG) is also memory
mapped. Read-modify-write operations on the LATG
register read and write the latched output value for
PORTG.
PORTG is multiplexed with EUSART2 functions
(Table 11-15). PORTG pins have Schmitt Trigger input
buffers.
When enabling peripheral functions, care should be
taken in defining TRIS bits for each PORTG 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
corresponding peripheral section for the correct TRIS
bit settings. The pin override value is not loaded into
the TRIS register. This allows read-modify-write of the
TRIS register without concern due to peripheral
overrides.

PORTG, TRISG and
LATG Registers
Although the port is only five bits wide, PORTG<7:5>
bits are still implemented. These are used to control the
weak pull-ups on the I/O ports associated with the
external memory bus (PORTD, PORTE and PORTJ).
Setting these bits enables the pull-ups. Since these are
control bits and are not associated with port I/O, the
corresponding TRISG and LATG bits are not
implemented.
