When main clock stop is detected when the CM20 bit is 1 (oscillation stop, re-oscillation detection func-
tion enabled), the MCU is initialized, coming to a halt (oscillation stop reset; refer to “SFR”, “Reset”).
This status is reset with hardware reset 1. Also, even when re-oscillation is detected, the MCU can be
initialized and stopped; it is, however, necessary to avoid such usage. (During main clock stop, do not set
the CM20 bit to 1 and the CM27 bit to 0.)
When the main clock corresponds to the CPU clock source and the CM20 bit is 1 (oscillation stop and re-
oscillation detect function enabled), the system is placed in the following state if the main clock comes to
a halt:
• Oscillation stop and re-oscillation detect interrupt request occurs.
• The on-chip oscillator starts oscillation, and the on-chip oscillator clock becomes the CPU clock and
• CM21 bit = 1 (on-chip oscillator clock for CPU clock source)
• CM22 bit = 1 (main clock stop detected)
• CM23 bit = 1 (main clock stopped)
When the PLL clock corresponds to the CPU clock source and the CM20 bit is 1, the system is placed in
the following state if the main clock comes to a halt: Since the CM21 bit remains unchanged, set it to 1
(on-chip oscillator clock) inside the interrupt routine.
• Oscillation stop and re-oscillation detect interrupt request occurs.
• CM22 bit = 1 (main clock stop detected)
• CM23 bit = 1 (main clock stopped)
• CM21 bit remains unchanged
When the CM20 bit is 1, the system is placed in the following state if the main clock re-oscillates from the
stop condition:
• Oscillation stop and re-oscillation detect interrupt request occurs.
• CM22 bit = 1 (main clock re-oscillation detected)
• CM23 bit = 0 (main clock oscillation)
• CM21 bit remains unchanged
