The High/Low-Voltage Detect (HLVD) module is a
programmable circuit that allows the user to specify
both the device voltage trip point and the direction of
change.

An interrupt flag is set if the device experiences an
excursion past the trip point in the direction of change.
If the interrupt is enabled, the program execution will
branch to the interrupt vector address and the software
can then respond to the interrupt.
The HLVD Control register (see
completely controls the operation of the HLVD module.
This allows the circuitry to be “turned off” by the user
under software control, which minimizes the current
consumption for the device.
