2.7
There are four CPU states: the reset state, program execution state, program halt state, and
exception-handling state. The program execution state includes active mode and subactive mode.
In the program halt state there are a sleep mode, standby mode, and sub-sleep mode. These states
are shown in figure 2.11. Figure 2.12 shows the state transitions. For details on program execution
state and program halt state, refer to section 6, Power-Down Modes. For details on exception
processing, refer to section 3, Exception Handling.
CPU States
CPU 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
