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
φ
W /4 internal clock is selected; otherwise halted and retained.
3.
Functions if
φ
W /2 is selected as the internal clock; otherwise halted and retained.
4.
Functions if
φ
W ,
φ
W /2 or
φ
W /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
φ
W /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
φ
W /32 is
selected as the internal clock; otherwise stops and stands by.
8.
Incrementing is possible, but interrupt generation is not.
9.
Functions if
φ
W /4 is selected as the internal clock; otherwise halted and retained.
10. On the H8/38124 Group, operates when
φ
W /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.
