11.4
PORTC is an eight-bit wide, bidirectional port. The
corresponding Data Direction and Output Latch registers
are TRISC and LATC. Only PORTC pins, RC2 through
RC7, are digital only pins.
PORTC is multiplexed with CCP, MSSP and EUSART
peripheral functions
Schmitt Trigger input buffers. The pins for CCP, SPI
and EUSART are also configurable for open-drain out-
put whenever these functions are active. Open-drain
configuration is selected by setting the SSPOD,
CCPxOD and U1OD control bits in the ODCON
register.
RC1 is configurable for open-drain output when CCP2
is active on this pin. Open-drain configuration is
selected
(ODCON<3>).

When enabling peripheral functions, use care in defin-
ing TRIS bits for each PORTC pin. Some peripherals
can override the TRIS bit to make a pin an output or
input. Consult the corresponding peripheral section for
the correct TRIS bit settings.
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.
