Section 2 CPU
2.8
2.8.1
The CPU has five main processing states: the reset state, exception handling state, program
execution state, bus-released state, and power-down state. Figure 2.11 shows a diagram of the
processing states. Figure 2.12 indicates the state transitions.

Overview
Exception-handling
Program execution
Bus-released state
Power-down state
The CPU and all on-chip supporting modules have been
initialized and are stopped.
A transient state in which the CPU changes the normal
processing flow in response to a reset, interrupt, or trap
instruction.
The CPU executes program instructions in sequence.
The external bus has been released in response to a bus
request signal from a bus master other than the CPU.
CPU operation is stopped
to conserve power.*
