Abstract

PURPOSE: To surely perform initial clear for the digital circuit at power supply application or intermittent power failure, by comparing the regulated voltage used for the digital circuit with the voltage slightly higher than the lower limit voltage operatable of the digital elements and by developing the initial clear signal based on this compared value.
