The internal interrupt sources include the general purpose timers 0, 1, and 2, and all of the
peripherals on the device. External interrupt sources include the three external interrupt lines, the
trip zones, and the external reset pin. The core has 14 interrupt lines. As you can see, the number
of interrupt sources exceeds the number of interrupt lines on the core. The PIE, or Peripheral
Interrupt Expansion block, is connected to the core interrupt lines 1 through 12. This block
manages and expands the 12 core interrupt lines, allowing up to 96 possible interrupt sources.
