ELECTRONIC EQUIPMENT, AND OPERATION STATE SWITCHING METHOD FOR ELECTRONIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To stably switch the output current of a power circuit when the electronic equipment is switched between its normal state and standby state. SOLUTION: When the electronic equipment is switched from the normal state to the standby state, a master clock 131 supplied in the normal state is stopped and a microcomputer power circuit operation mode switching signal XSTBY121 is outputted in a subclock operation state to switch the power source operation circuit mode to a small-current mode. When the equipment is switched from the standby state to the normal state, the microcomputer power circuit operation mode switching signal XSTBY121 is outputted in the sublock operation state to switch the power source operation circuit mode to a large-current mode, and then the master clock 131 begins to be supplied, so that the normal state is entered.
