<p><P>PROBLEM TO BE SOLVED: To provide a control device capable of continuously operating WDT function even when a rewriting setting signal becomes in the boot mode set state during execution of a control program of a micro-computer, and re-activating the micro-computer at a usual operation mode even when generation of resetting not intended in the state occurs. <P>SOLUTION: The electronic control device for the automobile has a circuit for latching a signal of the operation mode setting of the micro-computer capable of switching setting on function and automatic resetting cancel to WDT in the state immediately after throwing of an in-ECU system power source during a system power source is generated. Thereby, the micro-computer continuously operates the WDT function even when the rewriting setting signal becomes in the boot mode set state during execution of the control program, and the micro-computer is re-activated at the usual operation mode even when generation of resetting not intended in the state occurs. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
