CONTROLLER WITH RESETTING FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a controller which can forcibly reset a microprocessor from an inoperative state. SOLUTION: A controller provided with a resetting function which resets a built-in microprocessor 4 from an inoperative state forcibly resets the microprocessor 4 by generating a reset signal 30 from a microprocessor error signal 25 which recognizes the operation stop of the watch dog circuit 5 of the microprocessor 4 or by discriminating whether the microprocessor 4 is to be reset forcibly or to be held in the inoperative state by means of an automatic reset selecting switch 1 and inputting the reset signal 30 to a reset terminal RST.
