Operating Modes
The MCU has five operating modes that are specified by how the clock is used. The functions available in
each mode are listed in table 15, and operations are shown in table 16. Transitions between operating
modes are shown in figure 10. Table 17 provides additional information for table 15.

Notes: 1. To reduce current dissipation, stop all oscillation in external circuits.
2. Refer to the Interrupt Frame section for details.
3. Refer to table 17.
4. Subactive mode is an optional function, specify it on the function option list.
5. In the watch and subactive modes, the MCU requires a 32.768-kHz crystal oscillator.
