56 / 91 page  Rev.1.00 Sep 06, 2006 page 56 of 88 REJ03B0181-0100 3826 Group (One Time PROM version) Fig. 62 State transitions of system clock Notes 1: Switch the mode according to the arrows shown between the mode blocks. (Do not switch between the mode directly without an arrow.) 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: When the stop mode is ended, a delay time can be set by timer 1 and timer 2. 4: Timer and LCD operate in the wait mode. 5: Wait until oscillation stabilizes after oscillating the main clock before the switching from the low-speed mode to middle-/high-speed mode. 6: The example assumes that 8 MHz is being applied to the XIN pin and 32 kHz to the XCIN pin. φ indicates the system clock.
