8.7
PORTG is a 5-bit wide, bi-directional 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
hi-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).
Read-modify-write operations on the LATG register
read and write the latched output value for PORTG.
Pins RG0-RG2 on PORTG are multiplexed with the
CAN peripheral. Refer to "CAN Module", Section 17.0
for proper settings of TRISG when CAN is enabled.
