CM7 = 0
CM6 = 1
CM5 = 0 (8 MHz oscillating)
CM4 = 0 (32 kHz stopped)
Middle-speed mode
(f(
φ) = 1 MHz)
CM7 = 0
CM6 = 1
CM5 = 0 (8 MHz oscillating)
CM4 = 1 (32 kHz oscillating)
Middle-speed mode
(f(
φ) = 1 MHz)
CM7 = 0
CM6 = 0
CM5 = 0 (8 MHz oscillating)
CM4 = 0 (32 kHz stopped)
High-speed mode
(f(
φ) = 4 MHz)
CM7 = 1
CM6 = 0
CM5 = 0 (8 MHz oscillating)
CM4 = 1 (32 kHz oscillating)
Low-speed mode
(f(
φ)=16 kHz)
CM7 = 1
CM6 = 0
CM5 = 1 (8 MHz stopped)
CM4 = 1 (32 kHz oscillating)
Low-speed mode
(f(
φ)=16 kHz)
CM7 = 0
CM6 = 0
CM5 = 0 (8 MHz oscillating)
CM4 = 1 (32 kHz oscillating)
High-speed mode
(f(
φ) = 4 MHz)
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 bit 0 of MISRG is “0” and the stop mode is ended, a delay of approximately 1 ms occurs by connecting timer 1 in middle/high-speed
mode.
5 : When bit 0 of MISRG is “0” and the stop mode is ended, the following is performed.
(1) After the clock is restarted, a delay of approximately 256 ms occurs in low-speed mode if Timer 12 count source selection bit is “0”.
(2) After the clock is restarted, a delay of approximately 16 ms occurs in low-speed mode if Timer 12 count source selection bit is “1”.
6 : Wait until oscillation stabilizes after oscillating the main clock XIN 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 XIN pin and 32 kHz to the XCIN pin.
φ indicates the internal clock.
