Oscillation Stop Detectable Clock and
Frequency Bandwidth
Enabling Condition for Oscillation Stop,
Re-Oscillation Detection Function
Operation at Oscillation Stop,
Re-Oscillation Detection
The oscillation stop and re-oscillation detect function is such that main clock oscillation circuit stop and re-
oscillation are detected. At oscillation stop, re-oscillation detection, reset or oscillation stop, re-oscillation
detection interrupt are generated. Which is to be generated can be selected using the CM27 bit in the CM2 register.
The oscillation stop detection function can be enabled and disabled by the CM20 bit in the CM2 register. Table
10.9 lists a Specification Overview of Oscillation Stop and Re-Oscillation Detect Function.
Where main clock stop is detected when the CM20 bit is “1” (oscillation stop, re-oscillation detection function
enabled), the microcomputer is initialized, coming to a halt (oscillation stop reset; refer to 4. Special Function
Register (SFR), 5. Reset).
This status is reset with hardware reset 1 or hardware reset 2. Also, even when re-oscillation is detected, the
microcomputer 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”).
Where 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:
for CPU clock and peripheral functions in place of the main clock.
Where 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.
Where 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.
The on-chip oscillator starts oscillation, and the on-chip oscillator clock becomes the clock source
CM21 bit = 1 (on-chip oscillator clock for CPU clock source and clock source of peripheral function.)
CM22 bit = 1 (main clock stop detected)
CM23 bit = 1 (main clock stopped)
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
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
