PORTC and the TRISC Register
(2)
PORTC is an 8-bit bi-directional port. Each pin is individually configurable as an input or output
through the TRISC register. PORTC pins have Schmitt Trigger input buffers.
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 over-
ride the TRIS bit to make a pin an input.
