TRISC PORTC DATA DIRECTION
REGISTER
This register denes each pin of PORTC as either an
input or output under software control. A ‘1’ in each
location congures the corresponding port pin as an
input. This register resets to all ‘1’s, meaning all
PORTC pins are initially inputs. The data register
should be initialized prior to conguring the port as
outputs.
