7.0 INTERRUPTS

The interrupt feature allows certain events to preempt

normal program flow. Firmware is used to determine

the source of the interrupt and act accordingly. Some

interrupts can be configured to wake the MCU from

Sleep mode.

This chapter contains the following information for

Interrupts:

• Operation

• Interrupt Latency

• Interrupts During Sleep

• INT Pin

• Automatic Context Saving

Many peripherals produce interrupts. Refer to the

corresponding chapters for details.

A block diagram of the interrupt logic is shown in

Figure 7-1.
