PIC17C4X DEVICES
To enable the PORTB interrupt on change for PIC17C4X devices, you must clear the
following bit flags:
• The Peripheral Interrupt Request Register’s (PIR) PORTB Interrupt on Change
• The INTSTA register’s Peripheral Interrupt Flag (PEIF) bit – [INTSTA<7>]. This

There are two ways to enable the Capture1 Interrupt:
Library Call
To enable the Capture1 Interrupt through a library call, you must include the
captur16.
function also allows you to select the edge on which the interrupt occurs.
The following table outlines the
edge selection:
// Enable the Capture1 Interrupt on the specified edge
#ifdef _TRIGGER_ON_EVERY_RISING_EDGE
#elif defined _TRIGGER_ON_EVERY_FALLING_EDGE
#elif defined _TRIGGER_ON_EVERY_FOURTH_RISING_EDGE
#elif defined _TRIGGER_ON_EVERY_SIXTEENTH_RISING_EDGE
#endif
Flag (RBIF) bit – [PIR<7>].
clears any previous occurrences of PORTB interrupt. In addition, you must set the
following enable bits:
- The Peripheral Interrupt Enable Register’s (PIE) PORTB Interrupt on Change
- The INTSTA register’s Peripheral Interrupt Enable (PEIE) bit – [INTSTA<3>].
