Notes: 1. Register contents held; high-impedance output.
2. Functions only if external clock or φ_W/4 internal clock is selected; otherwise halted and retained.
3. Functions only if φ_W/2 internal clock is selected; otherwise halted and retained.
4. Functions only if φ_W or φ_W/2 internal clock is selected; otherwise halted and retained.
5. Functions when timekeeping time-base function is selected.
6. External interrupt requests are ignored. The interrupt request register contents are not affected.
