Fig. 56 State transitions of system clock
Low-power dissipation
mode (f(
φ) =16 kHz)
Notes 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 wait mode is ended.
3 : Timer and LCD operate in the wait mode.
4 : When the stop mode is ended, wait time can be set by connecting timer 1 and timer 2 in middle-/high-speed mode.
5 : When the stop mode is ended, wait time can be set by connecting timer 1 and timer 2 in low-speed mode.
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.
CM4 : Sub-clock (XCIN–XCOUT) stop bit
0: Stopped
1: Oscillating
CM5 : Main clock (XIN–XOUT) stop bit
0: Oscillating
1: Stopped
CM6 : Main clock division ratio selection bit
0: f(XIN)/2 (high-speed mode)
1: f(XIN)/8 (middle-speed mode)
CM7 : Internal system clock selection bit
0: XIN–XOUT selected
(middle-/high-speed mode)
1: XCIN–XCOUT selected
(low-speed mode)
