Functions if the timekeeping time-base function is selected.
External interrupt requests are ignored. Interrupt request register contents are not altered.
On the H8/38124 Group, operates when φ
otherwise stops and stands by. On the H8/38024, H8/38024S, and H8/38024R Group, operates when φ
selected as the internal clock; otherwise stops and stands by.
Incrementing is possible, but interrupt generation is not.
