NOTE
When switching from LPO to EPO, the user must be careful to ensure that
the EPO has been enabled and powered up long enough to stabilize before
shifting clock sources.
IRQF — External Interrupt Request Flag
The IRQF flag is a clearable, read-only bit that is set when an external interrupt request is pending.
Refer to Chapter 4 Interrupts for more details.
IRQR — Interrupt Request Reset Bit
This write-only bit clears the IRQF flag bit and prevents redundant execution of interrupt routines. Refer
to Chapter 4 Interrupts for more details.
6.3 Low-Power Modes
Four modes of operation reduce power consumption:
Stop mode
Wait mode
Halt mode
Data-retention mode
Figure 6-2 shows the sequence of events in stop, wait, and halt modes.
