2.1.2.1 Supply Supervisors

Two supply supervisor circuits are available:

The fixed power-on reset (POR) circuit to indicate that the external supply has reached sufficient for the device to run correctly.

The user-programmable brownout reset (BOR) circuit, which ensures that the external supply is maintained at a sufficient voltage to support correct operation of the device, which can be configured to other three BOR levels after startup.
