Pull-up resistance of RES pin
Power-on reset start voltage*
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.
