10.4
PORTC is an 8-bit wide, bidirectional port. The corre-
sponding Data Direction register is TRISC. Setting a
TRISC bit (= 1) will make the corresponding PORTC
pin an input (i.e., put the corresponding output driver in
a high-impedance mode). Clearing a TRISC 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 (LATC) is also memory
mapped. Read-modify-write operations on the LATC
register read and write the latched output value for
PORTC.
PORTC is multiplexed with several peripheral functions
(see Table 10-7). The pins have Schmitt Trigger input
buffers.
When enabling peripheral functions, care should be
taken in defining TRISx bits for each PORTC pin. Some
peripherals override the TRISx bit to make a pin an out-
put, while other peripherals override the TRISx bit to
make a pin an input. The user should refer to the
corresponding
information.

Preliminary
The contents of the TRISC register are affected by
peripheral overrides. Reading TRISC always returns
the current contents, even though a peripheral device
may be overriding one or more of the pins.

On a Power-on Reset, PORTC pins
(except RC2) are configured as digital
inputs. RC2 will default as an analog input
(controlled by the ANCON1 register).
