(1) If the on/off latched data is changed from “0” to “1” at 1’st LAT signal, changed from “1” to “0” at second LAT signal.
(2) If the on/off latched data is changed from “0” to “1” at 1’st LAT signal, changed from “1” to “1” at second LAT signal.
(3) If the on/off latched data is changed from “1” to “0” at 1’st LAT signal, changed from “0” to “1” at second LAT signal.
(4) if the on/off latched data is “0”.
