TABLE 10-7:

PORTC is an 8-bit wide, bidirectional port. Only
PORTC pins, RC2 through RC7, are digital only pins
and can tolerate input voltages up to 5.5V.
PORTC is multiplexed with ECCP, MSSP and EUSART
peripheral functions (Table 10-8). The pins have
Schmitt Trigger input buffers. The pins for ECCP, SPI
and EUSART are also configurable for open-drain out-
put whenever these functions are active. Open-drain
configuration is selected by setting the SPIxOD,
ECCPxOD, and UxOD control bits in the ODCON reg-
isters (see Section 10.1.3 “Pull-up Configuration”
for more information).
RC1 is normally configured as the default peripheral
pin for the ECCP2 module. Assignment of ECCP2 is
controlled by Configuration bit, CCP2MX (default state,
CCP2MX = 1).
When enabling peripheral functions, care should be
taken in defining TRIS bits for each PORTC 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 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.
