Fig. 48 State transitions of system clock
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
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
5 : When bit 0 of MISRG is “0” and the stop mode is ended, the following is performed.
6 : Wait until oscillation stabilizes after oscillating the main clock X
7 : The example assumes that 8 MHz is being applied to the X
