Notes: 1. Register contents are retained, but output is high-impedance state. Port 5 of the HD64F38024 retains the previous
pin state.
2. Functions if an external clock or the φW/4 internal clock is selected; otherwise halted and retained.
3. Functions if φW/2 is selected as the internal clock; otherwise halted and retained.
4. Functions if φW, φW/2 or φW/4 is selected as the operating clock; otherwise halted and retained.
5. Functions if the timekeeping time-base function is selected.
6. External interrupt requests are ignored. Interrupt request register contents are not altered.
7. On the H8/38124 Group, operates when φW/32 is selected as the internal clock or the on-chip oscillator is selected;
otherwise stops and stands by. On the H8/38024, H8/38024S, and H8/38024R Group, operates when φW/32 is
selected as the internal clock; otherwise stops and stands by.
8. Incrementing is possible, but interrupt generation is not.
9. Functions if φW/4 is selected as the internal clock; otherwise halted and retained.
10. On the H8/38124 Group, operates when φW/32 is selected as the internal clock or the on-chip oscillator is selected;
otherwise stops and stands by. On the H8/38024, H8/38024S, and H8/38024R Group, stops and stands by.
