High-speed mode
(f(
φ) = 4 MHz)
CM7=0
CM6=0
CM5=0 (8 MHz oscillating)
CM4=0 (32 kHz stopped)
High-speed mode
(f(
φ) = 4 MHz)
CM7=0
CM6=0
CM5=0 (8 MHz oscillating)
CM4=1 (32 kHz oscillating)
Notes 1: Switch the mode by the allows shown between the mode blocks. (Do not switch between the modes directly without an
allow.)
2: The all modes can be switched to the stop mode or the wait mode and return to the source mode when the stop mode or the
wait mode is ended.
3: Timer operates in the wait mode.
4: When the stop mode is ended, a delay of approximately 1 ms occurs by connecting prescaler 12 and Timer 1 in middle/high-
speed mode.
5: When the stop mode is ended, a delay of approximately 0.25 s occurs by Timer 1 and Timer 2 in low-speed mode.
6: Wait until oscillation stabilizes after oscillating the main clock X IN before the switching from the low-speed mode to middle/
high-speed mode.
7: The example assumes that 8 MHz is being applied to the X IN pin and 32 kHz to the XCIN pin.
φ indicates the internal clock.
Middle-speed mode
(f(
φ) = 1 MHz)
CM7=0

Low-speed mode
(f(
φ) = 16 kHz)
CM7=1
CM6=0
CM5=0 (8 MHz oscillating)
CM4=1 (32 kHz oscillating)
Low-speed mode
(f(
φ) = 16 kHz)
