The brown-out reset (BOR) is an internal supply voltage supervisor (SVS) circuit that monitors the VDDIO supply for glitches or supply interruptions. If the VDDIO supply voltage drops below operational voltage range, this circuit forces the XRSn pin low until the fault is removed and the supply voltage returns to the minimum operational voltage. A BOR resets everything in the same manner as a POR reset.
The BOR circuit is enabled by default and is always active during power up or after any type of reset. To disable the BOR circuit, set the BORLVMONDIS bit in the VMONCTL register.
