PIC17C4X DEVICES
To enable the TMR3 overflow interrupt for PIC17C4X devices, you must clear the
following bit flags:
• The Peripheral Interrupt Request Register’s (PIR) TMR3 Interrupt Flag (TMR3IF)
• The Timer3 On (TMR3ON) bit – [TCON2<2>]. This stops the timer until you are
• The INTSTA register’s Peripheral Interrupt Flag (PEIF) bit – [INTSTA<7>]. This
ALL PIC17 DEVICES
To reset Timer3, you must clear the TMR3L and TMR3H registers.
To start Timer3, set the Timer3 On (TMR3ON) bit – [TCON2<2>].
11.3.2.7
There are two ways to enable the PORTB Interrupt on Change:
Library Call
To enable the PORTB interrupt on change through a library call, you must include the
port16.h
Modifying Register Bits
PIC17C7XX DEVICES
To enable the PORTB interrupt on change for PIC17C7XX devices, you must clear the
following bit flags:
• The Peripheral Interrupt Request Register1’s (PIR1’s) PORTB Interrupt on
• The INTSTA register’s Peripheral Interrupt Flag (PEIF) bit – [INTSTA<7>]. This
bit – [PIR<6>].

clears any previous occurrences of TMR3 overflow interrupts. In addition, you
must set the following enable bits:
- The Peripheral Interrupt Enable Register’s (PIE) TMR3 Interrupt Enable
- The INTSTA register’s Peripheral Interrupt Enable (PEIE) bit – [INTSTA<3>].
#include <port16.h>
