Power supplies DV
brownout monitor that alerts the µC through interrupt
when their corresponding supply voltages drop below
a selectable threshold. This condition is generally
referred to as brownout interrupt (BOI), and these
thresholds are set by the VDBI and VIOBI bits for DV
and DV
ensures that a valid supply is present at all times while
the µC is executing code. For example, the brownout
