6.4.2 Stop Re c ove ry
The processor can be brought out of the stop mode only by an external
interrupt or RESET. See Figure 6-2.
6.4.3 Wa it Mod e
The WAIT instruction places the MCU in a low power-consumption
mode, but the wait mode consumes more power than the 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 the wait mode. The user must shut off subsystems to reduce
power consumption. WAIT current specifications assume CPU
operation only and do not include current consumption by any other
subsystems.
