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 Timer 1 in middle/high-speed mode.
5 :
When the stop mode is ended, the following is performed.
(1) After the clock is restarted, a delay of approximately 16ms occurs in low-speed mode if Timer 12 count source selection bit is "0".
(2) After the clock is restarted, a delay of approximately 250ms occurs in low-speed mode if Timer 12 count source selection bit is "1".
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 X
CIN
pin. f indicates the internal clock.
