Section 2 CPU
2.8
The H8S/2000 CPU has five main processing states: the reset state, exception handling state,
program execution state, bus-released state, and program stop state. Figure 2.13 indicates the state
transitions.
• Reset state
• Exception-handling state
• Program execution state
• Bus-released state
• Program stop state
Rev.7.00 Mar. 18, 2009 page 68 of 1136
REJ09B0109-0700
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, refer to section 4, Exception Handling.
The reset state can also be entered by a watchdog timer overflow.
The exception-handling state is a transient state that occurs when the CPU alters the normal
processing flow due to an exception source, such as, a reset, trace, interrupt, or trap instruction.
The CPU fetches a start address (vector) from the exception vector table and branches to that
address. For further details, refer to section 4, Exception Handling.
In this state the CPU executes program instructions in sequence.
In a product which has a DMA controller and a data transfer controller (DTC), 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,
refer to section 24, Power-Down Modes.
