Microcomputer controlled apparatus provided with a battery voltage detection circuit

摘要

In a microcomputer controlled apparatus there is provided a device for memorizing that the battery voltage has dropped below a predetermined value and a control device for stopping the execution of the program. Subsequently if the battery voltage rises and execution of the program is restarted, the control device determines from the memorizing device that a voltage drop occurred and forcedly stops the execution of the program until the old discharged battery is replaced with a new fully charged battery.
