Figure 6-1. Stop Recovery Timing Diagram
6.4 Stop Recovery
The processor can be brought out of stop mode only by an external
interrupt, LPRST, or RESET. Refer to Figure 6-1.
NOTE:
If an external interrupt is pending when stop mode is entered, then stop
mode will be exited immediately.
6.5 Wait Mode
The WAIT instruction places the MCU in a low power-consumption
mode, but wait mode consumes more power than stop mode. All CPU
action is suspended, but the core timer, the oscillator, and any enabled
module remain active. Any interrupt or reset will cause the MCU to exit
wait mode. The user must shut off subsystems to reduce power
