1: Switch the mode by the allows shown between the mode blocks. (Do not switch between the mode directly without an allow.)
2: The all modes can be switched to the stop mode or the wait mode and returned to the source mode when the stop mode or the wai
mode is released.
3: Timer and LCD operate in the wait mode.
4: In middle-/high-speed mode, when the stop mode is released, a delay of approximately 1 ms occurs automatically by timer 1 and
timer 2.
5: In low-speed mode, when the stop mode is released, a delay of approximately 0.25 s occurs automatically by timer 1 and timer
6: Wait until oscillation stabilizes after oscillating the main clock
speed mode.
7: The example assumes that 8 MHz is being applied to the XIN pin and 32 kHz to the XCIN pin.
φ indicates the internal clock.
