NOTE:
The EIMSK bit of the carrier modulator transmitter MCSR (modulator
control and status register) is not cleared automatically by the execution
of a STOP instruction. Care should be taken to clear this bit before
entering stop mode.
6.4 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
consumption. Wait current specifications assume CPU operation only
and do not include current consumption by any other subsystems.
