PIC18F2480/2580/4480/4580
High/Low-Voltage Detect module (HLVD). 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 device experiences 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 interrupt vector
address and the software can then respond to the
interrupt.

The
(Register 23-1) 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.
