There are three CPU operation states, namely, program execution state, power-down state, and
exception-handling state. In power-down state there are sleep mode, standby mode, and watch
mode. These operation states are shown in figure 3-1. Figure 3-2 shows the state transitions.
For further details please refer to the applicable hardware manual.
State
A state in which some or all
of the chip functions are
stopped to conserve power.
A transient state in which the CPU changes
the processing flow due to a reset or an interrupt.
