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 mode, standby mode,
watch mode, and sub-sleep mode. These states are shown in figure 2.14.
Figure 2.15 shows the state transitions.
