The PIC microcontroller has several sources of interrupts. Here are some of them:

1. External Interrupts: These are triggered by external events on specific pins of the PIC microcontroller. For example, a button press or a signal from another device.

2. Timer Interrupts: These are triggered when a timer overflows, i.e., when it counts up to its maximum value and resets to zero.

3. Peripheral Interrupts: These are triggered by events in the PIC's peripherals, such as the completion of an analog-to-digital conversion, the reception of a byte via the serial port, etc.

4. Software Interrupts: These are triggered by the execution of specific instructions in the PIC's instruction set, such as the "interrupt on change" feature, which generates an interrupt when the state of a specific pin changes.

5. Watchdog Timer Interrupt: This is triggered when the watchdog timer overflows. The watchdog timer is a special timer that resets the microcontroller if it overflows, which is useful for recovering from software errors.

6. Low Voltage Detect Interrupt: This is triggered when the supply voltage drops below a certain level.

7. Oscillator Fail Detect Interrupt: This is triggered when the PIC's oscillator fails.

8. Comparator Interrupt: This is triggered when the input voltages to the comparator match.

Each of these interrupt sources can be enabled or disabled individually, and they each have a specific priority level that determines the order in which they are handled if multiple interrupts occur at the same time.
