Notes:
1. Register contents are retained, but output is high-impedance state.
2. Functions if an external clock or the øW/4 internal clock is selected; otherwise halted and retained.
3. Functions if øW/2 is selected as the internal clock; otherwise halted and retained.
4. Functions if øW or øW/2 or øW/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. Functions if øW/32 is selected as the internal clock; otherwise halted and retained.
8. Incrementing is possible, but interrupt generation is not.
9. Functions if øW/4 is selected as the external or internal clock; otherwise halted and retained.
