Caution When the LVD is off, it is necessary to perform an external reset. For an external reset, input a low
level of at least 10
s or more to the RESET pin. To perform an external reset upon power application,
input a low level to the RESET pin before power-on, keep the low level for at least 10
s during the
period in which the supply voltage is within the operating range, and then input a high level. After
power is applied, do not input a high level to the RESET pin during a period in which the supply
voltage is not within the operating range.
