Figure 6-1. Stop Recovery Timing Diagram
6.4 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, SCI, 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.
