3.6 CPU States
The CPU has three states: the program execution state, exception-handling state, and power-down
state. The power-down state is further divided into three modes: the sleep mode, software standby
mode, and hardware standby mode. Figure 3-11 summarizes these states, and figure 3-12 shows a
map of the state transitions.
State
— H8/300 CPU will malfunction after EEPMOV instruction execution.
— Please use EEPMOV when the destination is in the internal area (e.g. internal RAM).
— When the destination is the external area, please avoid wait state insertion to the bus cycle.
— When the case that wait state(s) is required, please substitute EEPMOV by MOV and other
Please take at least one counter measure from the followings.

LOOP
The CPU executes successive program instructions.
A transient state triggered by a reset or interrupt. The CPU executes a hardware
sequence that includes loading the program counter from the vector table.
A state in which some or all of the chip
functions are stopped to conserve power.
