Abstract
PURPOSE: To prevent the malfunction and at the same time reduce the amount of power consumption, by using the micro CPU and ROM with the power supply control device using the microprocessor and having a high degree of freedom for the control and thus securing a control with a higher degree of freedom for the on/off of the power supply, the on/off of the input power supply end the value of voltage each.
CONSTITUTION: During the on and off of the input power supply, the data of the ROM read out onto the data bus DBS is held at the output port OP by decoding the reset subroutine program of the ROM and the switch command given from the signal DTS. Accordingly, the driving signal is produced at the driving circuit DRV. The output of the circuit DRV is delayed by the delay circuit DLC until the micro CPUMPU becomes normal to then drive the power supply circuit PSC. As a result, a control is possible with a higher degree of freedom for the on/off of the power supply, the on/off of the input power supply and the value of voltage each. Thus the malfunction can be prevented, at the same time reducing the amount of power consumption.
