PORTG, TRISG and LATG
Registers
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 PORTC pin an output (i.e.,
put the contents of the output latch on the selected pin).
The Data 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 both CCP and USART
functions (Table 10-13). 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 reg-
ister. This allows read-modify-write of the TRIS register,
without concern due to peripheral overrides.
