Register Descriptions

Configuration

STATUS

OPTION

INTCON

PIE1

The PIE1 is used to enable/disable interrupts.

I/O

PORTA

TRISA

ANSEL

The ANSEL register determines whether a pin, AN<7:0>, is an analog input or not.

IOCA

The IOCA register determines whether or not an interrupt is generated when a digital pin on PORTA, RA<5:0>, experiences a change in value.

PORTC

TRISC
