2.2.2
WAIT mode
The WAIT instruction places the MCU in a low power consumption mode, though it consumes
more power than in STOP mode. All CPU action is suspended, but the core timer and the 16-bit
timer remain active. An interrupt from the core timer, 16-bit timer, IRQ, keyboard, LVI, if enabled,
will cause the MCU to exit the WAIT mode. An external reset, or LVR, causes 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 DMG is still active during WAIT mode.
