drops below the VBO threshold voltage (unsafe level). While the supply voltage remains
below the Power-On Reset threshold voltage (V

After the supply voltage exceeds the Power-On Reset threshold voltage, the device
progresses through a full system reset sequence, as described in the POR section.
Following Power-On Reset, the POR status bit in the reset status (RSTSTAT) register is
set to 1.

The POR level is greater than the VBO level by the specified hysteresis value. This
ensures that the device undergoes a POR after recovering from a VBO condition.
