摘要：
A system ROM stores a control program for measuring an internal operation state of a CPU unit, and a data RAM stores a measured internal operation state of the CPU unit. The internal operation measuring control program enables the internal operation state of the CPU unit to be measured in response to a monitor processing request from an external peripheral device, and a measurement result to be sent to the external peripheral device, to thereby allow the external peripheral device to monitor the internal operation state of the CPU unit.
