TABLE 10-15: SUMMARY OF REGISTERS ASSOCIATED WITH PORTF
10.8
PORTG is a 5-bit wide, bidirectional port. All pins on
PORTG are digital only and tolerate voltages up to
5.5V.
PORTG is multiplexed with EUSART2 functions
(Table 10-16). PORTG pins have Schmitt Trigger input
buffers. PORTG is also multiplexed with address and
control functions of the Parallel Master Port.
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.

Although the port itself 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 asso-
ciated 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.
