• Description: 28-Pin Programmable Mixed Signal Controller
• Manufacturer: Microchip Technology

5.2.1
This register defines each pin of PORTC as either an
input or output under software control. A ‘1’ in each
location configures 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 configuring the port as
outputs.
