Section 2 CPU
2.8
2.8.1
The H8/300H CPU has five processing states: the program execution state, exception-handling
state, power-down state, reset state, and bus-released state. The power-down state includes sleep
mode, software standby mode, and hardware standby mode. Figure 2.11 classifies the processing
states. Figure 2.13 indicates the state transitions.
2.8.2
In this state the CPU executes program instructions in normal sequence.

Overview
Program Execution State
Exception-handling state
Program execution state
The CPU executes program instructions in sequence
A transient state in which the CPU executes a hardware sequence
(saving PC and CCR, fetching a vector, etc.) in response to a reset,
interrupt, or other exception
The external bus has been released in response to a bus request
signal from a bus master other than the CPU
The CPU and all on-chip supporting modules are initialized and halted
The CPU is halted to conserve power
