Section 2 CPU
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.
For 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.
