Low-Power Modes
6.3 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 timer, serial communications
interface (SCI), serial peripheral interface (SPI), and the oscillator remain active. Any interrupt or reset will
cause the MCU to exit the wait mode.
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 state. The timer, SCI, and SPI may be enabled to allow a
periodic exit from the wait mode.
