- Compare-match detected
When a match between a count value and a count comparison value is detected, the
indicator "comparison match detected" is stored.
To reset this condition, either output a value to the "comparison match detection
reset" bit or perform a "channel reset" operation.
- Abnormal input detected
When abnormal input is detected, the system stores an "abnormal input detected"
value.
In the case of a mono-phase counter, the simultaneous input of UP and DOWN
pulses causes the detection of abnormal input.
In the case of a 2-phase counter, if both phases A and B change simultaneously,
abnormal input is detected as an abnormal state transition.
To reset this condition, either output a value to the "abnormal input detection reset"
bit or perform a "channel reset" operation.
- General-purpose input
Indicates the status of general-purpose input.
