<p>PROBLEM TO BE SOLVED: To reduce the power consumption of an initializing process and to makes a power unit small-sized and lightweight by generating a plurality of cycles of writing operation for initial data to the storage device, selecting those cycles from the outside, and writing initial data in the storage device in the selected cycles. SOLUTION: When a power source is turned on, a cycle switching means 5 sends out an initialization cycle select signal 11 for setting cycles of writing operation to the storage device 6 with an initialization signal 10 from an initializing circuit 1. Further, an initialization timing control circuit 4 generates a plurality of cycles of writing operation by the initializing signal 10 and selects one of the cycles by an initialization cycle select signal 11. Then, a memory control circuit 3 when receiving the initialization signal 10 in the timing of this cycle informs a write instruction part 31 of that and a write instruction part 31 generates a write instruction 13 for writing predetermined initial data to the storage device 6.</p> |
