Abstract

PURPOSE:To avoid resetting of a microprocessor under normal processing action, by preventing the resetting action during the processing action in the case of the processing action within a certain time and the processing action that possibly exceeds a certain time, respectively. CONSTITUTION:Both an originating button signal GBS and an incoming detection signal TDS are used as the inputs, and a counter CONT is cleared via an OR gate circuit OR1, a 1-shot circuit OS plus an OR gate circuit OR2, respectively. At the same time, the operation of a multivibrator MV is stopped by an off-hook signal HOS based on the detection of operation of a relay L that detects the off-hook, and the clock signal, i.e., the output of the vibrator MV is stopped. Then the operation of a timing circuit is inhibited to prevent the resetting action.
