17.2 Functional Description
The following figure illustrates the operation of the POR versus low voltage detect
circuits. The interrupt service routine responsible for shutting down the device when a
low voltage is detected should explicitly clear and disable the low-voltage interrupts.
Low-voltage interrupts are masked at POR. Afterwards, they must be explicitly enabled
and disabled. Low-voltage interrupts include roughly 50mV of hysteresis.
