The PIC16F72X/PIC16LF72X device family features
an interruptible core, allowing certain events to
preempt normal program flow. An Interrupt Service
Routine (ISR) is used to determine the source of the
interrupt and act accordingly. Some interrupts can be
configured to wake the MCU from Sleep mode.

• External Edge Detect on INT Pin Interrupt
• PORTB Change Interrupt
• Timer1 Gate Interrupt
• A/D Conversion Complete Interrupt
• AUSART Receive Interrupt
• AUSART Transmit Interrupt
• SSP Event Interrupt
• CCP1 Event Interrupt
• Timer2 Match with PR2 Interrupt
• Timer1 Overflow Interrupt
• CCP2 Event Interrupt
A block diagram of the interrupt logic is shown in

Some peripherals depend upon the
system clock for operation. Since the
system clock is suspended during
Sleep, these peripherals will not wake
the part from Sleep. See Section 19.1
“Wake-up from Sleep”.
