WAIT
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 in WAIT
mode. The oscillator, and the timers and SCI if enabled, remain active. Any interrupt or any
form of Reset will cause the MCU to exit the WAIT mode.
During the WAIT mode, the I bit in the CCR is cleared to enable interrupts. The IRQE bit in
the Configuration Register is set to allow an IRQ interrupt to force the MCU out of WAIT.
All other registers, memory, and input/output lines remain in their previous state.
