7.5 Wait Mode
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 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.
During wait mode, the I bit in the CCR is cleared to enable interrupts. All
other registers, memory, and input/output lines remain in their previous
states. The timer can be enabled to allow a periodic exit from wait mode.
7.6 Low-Power Reset
Low-power reset mode is entered when a logic 0 is detected on the
LPRST pin. When in this mode (as long as LPRST is held low), the MCU
is held in reset and all internal clocks and the crystal oscillator (if used)
are halted. Applying a logic 1 to LPRST will cause the part to exit low-
power reset mode and begin counting out the 4064-cycle oscillator
stabilization period. Once this time has elapsed, the MCU will begin
operation from the reset vectors ($3FFE–$3FFF).
