Three-state access to on-chip peripheral modules
2.7
2.7.1
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. In the program halt state there are a sleep (high-speed or
medium-speed) mode, standby mode, watch mode, and sub-sleep mode. These states are shown in
figure 2.14. Figure 2.15 shows the state transitions.
