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.

Processing states
Processing States
Overview
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
Bus-released state
