External Interrupt (IRQ)
17.1 Introduction
The external interrupt (IRQ) module provides two maskable interrupt inputs: IRQ1 and IRQ2.
17.2 Features
Features of the IRQ module include:
17.3 Functional Description
A logic 0 applied to the external interrupt pin can latch a CPU interrupt request.
Figure 17-3
Interrupt signals on the IRQ pin are latched into the IRQ latch. An interrupt latch remains set until one of
the following actions occurs:

An external interrupt pin shared with a port pin, PTC0/IRQ2
Separate IRQ interrupt control bits for IRQ1 and IRQ2
Hysteresis buffers
Programmable edge-only or edge and level interrupt sensitivity
Automatic interrupt acknowledge
Internal pullup resistor, with disable option on IRQ2
Vector fetch — A vector fetch automatically generates an interrupt acknowledge signal that clears
the latch that caused the vector fetch.

References to either IRQ1 or IRQ2 may be made in the following text by
omitting the IRQ number. For example, IRQF may refer generically to
IRQ1F and IRQ2F, and IMASK may refer to IMASK1 and IMASK2.
