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