摘要： PROBLEM TO BE SOLVED: To facilitate control and reduce power consumption by enabling instructions without depending on the times of an initializing process and an ending process for a system to be controlled. SOLUTION: A power supply control signal 503 input from a host CPU is input to an internal delay circuit part 501. After a delay for a certain period of time preset in a nonvolatile memory 501a of the delay circuit part 501 from an internal local bus, the state of a control signal 504 is changed and the control signal is input to the next power control circuit part 502. The change in state of the control signal 504 is to make the level of the signal high or low. The power control circuit part 502 turns a control power supply 505 on or off according to the change in state of the control signal 504 input, thereby controlling the power supply of each device. Setting the delay time is based on a delay time written into a program previously stored in a ROM. The delay time is written into the nonvolatile memory 501a under control of the CPU on start-up.
