Note:

The power-supply voltage (Vcc) must fall below Vpor = 100 mV and then rise after

charge of the

RES pin is removed completely. In order to remove charge of the RES

pin, it is recommended that the diode be placed in the Vcc side. If the power-supply

voltage (Vcc) rises from the point over 100 mV, a power-on reset may not occur.
