S-35L12A internal power voltage detecting circuit. This circuit gives sampling movement only 15.6 once second. power voltage decreases below detection voltage (VDET), latch circuit latches level, sampling movement stops. Only when subsequent communication status read command, output latch circuit transferred sift register sampling movement resumed. Decrease power voltage monitored reading POWER flag. That say, once decrease power voltage detected, detecting operation performed held unless perform initialization send status read command. Caution When power voltage increased first read operation performed after decrease power voltage occurs latch circuit latches "H", read POWER flag, however, next read operation performed after sampling detecting circuit, POWER flag reset since sampling subsequently allowed. timing diagram below.
