25.0
The High/Low-Voltage Detect (HLVD) module can be
used to monitor the absolute voltage on V
HLVDIN pin. This is a programmable circuit that allows
the user to specify both a device voltage trip point and
the direction of change from that point.
If the module detects an excursion past the trip point in
that direction, an interrupt flag is set. If the interrupt is
enabled, the program execution will branch to the inter-
rupt vector address and the software can then respond
to the interrupt.

0 = Event occurs when the voltage equals or falls below the trip point (HLVDL<3:0>)
BGVST: Band Gap Reference Voltages Stable Status Flag bit
1 = Indicates internal band gap voltage references is stable
0 = Indicates internal band gap voltage reference is not stable
IRVST: Internal Reference Voltage Stable Flag bit
1 = Indicates that the voltage detect logic will generate the interrupt flag at the specified voltage range
0 = Indicates that the voltage detect logic will not generate the interrupt flag at the specified voltage

The
(Register 25-1) 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.

module.
