Overview
The CPU operates in three states: the program execution state, exception-handling state, and
power-down state. Figure 2.11 summarizes these states. Figure 2.12 shows the state transitions.
Chip state
Program execution state
CPU executes program
Exception-handling state
Transitory state that changes CPU execution flow
at a reset or interrupt
Power-down state
CPU halts to conserve power
Sleep mode
