Notes: 1. Register contents are retained. Output is the high-impedance state.
2. Functioning if φ
W
/4, φ
W
/256, or φ
W
/1024 is selected as an internal clock. Halted and retained otherwise.
3. Functioning if φ
W
/4 is selected as an internal clock. Halted and retained otherwise.
4. Functioning if the on-chip WDT oscillator is selected or if φ
W
/16, or φ
W
/256 is selected as an internal clock. Halted
and retained otherwise.
5. Functioning if the on-chip WDT oscillator is selected. Halted and retained otherwise.
6. Functioning if φ
W
/2 is selected as an internal clock. Halted and retained otherwise.
7. Functioning if φ
W
, φ
W
/2, or φ
W
/4 is selected as an internal clock. Halted and retained otherwise.
8. Functions if the RTC operation is selected as a clock source. Halted and retained for the free-running counter.
