The POR will generate keep reset_out_n low between 75ms and 300ms after 3.3V reaches the POR reference trip voltage threshold. The POR reference trip voltage is between 2.74V and 2.97V, with hysteresis between 50mV and 80mV.

If the POR feature is not used, and the RTC is used, the inputs must be terminated as shown below.
