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 (high-speed or medium-
speed) mode and subactive mode. For the program halt state, there are sleep (high-speed or
medium-speed) mode, standby mode, watch mode, and subsleep 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 5, Power-Down Modes. For details on exception handling, refer
to section 3, Exception Handling.
