After the supply voltage again exceeds the POR voltage threshold and stabilized, the
device progresses through a full System Reset sequence, as described in the Power-on
reset section. Following POR, the POR status bit in the Reset Source register is set to 1.

The input-only RESET pin has a Schmitt-triggered input, an internal pull-up, an analog
filter, and a digital filter to reject noise. When the RESET pin is asserted for at least
4 system clock cycles, the device progresses through the System Reset sequence. While
