Notes:
1. Register contents are retained, but output is high-impedance state.
2. Functions if ø_W/2 is selected as the internal clock; otherwise halted and retained.
3. Functions if ø_W, ø_W/2 or ø_W/4 is selected as the operating clock; otherwise halted and retained.
4. Functions if the timekeeping time-base function is selected.
5. External interrupt requests are ignored. Interrupt request register contents are not altered.
6. Incrementing is possible, but interrupt generation is not.
7. Functions if the ø_W/4 internal clock is selected; otherwise halted and retained.
