state either by returning them to their initial state with a reset or by setting the POECMPFR.CnFLAG flag (n = 0 to 2) to
0.
When setting the POECMPFR.CnFLAG flag to 0, be sure to confirm that the analog input signal that triggered
comparator output detection has returned to a normal value by performing A/D conversion and so on.
Note that the above POECMPFR.CnFLAG flag is not set to 1 again in the following cases:
- This flag is cleared without confirmation that the analog input signal has returned to a normal value, and
1. the analog input signal remains above the reference voltage when the comparator is set to non-inverted output, or
2. the analog input signal remains below the reference voltage when the comparator is set to inverted output.
The outputs which have been in the high-impedance state due to oscillation stop detection can be recovered from the
state either by returning them to their initial state with a reset or by setting the SYSTEM.OSTDSR.OSTDF flag to 0 to
set the ICSR6.OSTSTF flag to 0.
