Section 2 CPU
2.9
The H8SX CPU has five main processing states: the reset state, exception-handling state, program
execution state, bus-released state, and program stop state. Figure 2.16 indicates the state
transitions.
• Reset state
• Exception-handling state
• Program execution state
• Bus-released state
• Program stop state

REJ09B0414-0200
In this state the CPU and internal peripheral modules are all initialized and stopped. When the
RES input goes low, all current processing stops and the CPU enters the reset state. All
interrupts are masked in the reset state. Reset exception handling starts when the RES signal
changes from low to high. For details, see section 4, Resets and section 5, Exception Handling.
The exception-handling state is a transient state that occurs when the CPU alters the normal
processing flow due to activation of an exception source, such as, a reset, trace, interrupt, or
trap instruction. The CPU fetches a start address (vector) from the exception handling vector
table and branches to that address. For further details, see section 4, Resets and section 5,
Exception Handling.
In this state the CPU executes program instructions in sequence.
The bus-released state occurs when the bus has been released in response to a bus request from
a bus master other than the CPU. While the bus is released, the CPU halts operations.
This is a power-down state in which the CPU stops operating. The program stop state occurs
when a SLEEP instruction is executed or the CPU enters hardware standby mode. For details,
see section 24, Power-Down Modes.
Request for exception
Note: In any state, when the STBY signal goes low, a transition to the hardware standby mode occurs.
Processing States
* In any state except the hardware standby mode, when the RES signal goes low, a transition
handling
to the reset state occurs. A transition to the reset state can also be made without driving
the RES signal low. For details, see section 4, Resets.
