SECTION 6
LOW POWER MODES
There are three modes of operation that reduce power consumption:
Stop mode
Wait mode
Halt mode
The WAIT and STOP instructions provide two power saving modes by stopping
various internal modules and/or the on-chip oscillator. The STOP and WAIT
instructions are not normally used if the COP Watchdog Timer is enabled. A mask
option is provided to convert the STOP instruction to a HALT, which is a WAIT-like
instruction that does not halt the COP Watchdog Timer but has a recovery delay.
The flow of the STOP, HALT, and WAIT modes are shown in
Figure 6-1
