17.0
PIC18F2450/4450 devices have a 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.

0 = Event occurs when voltage equals or falls below trip point (HLVDL3:HLVDL0)
Unimplemented: Read as ‘0’
IRVST: Internal Reference Voltage Stable Flag bit
1 = Indicates that the voltage detect logic will generate the interrupt flag at the specified voltage
0 = Indicates that the voltage detect logic will not generate the interrupt flag at the specified voltage

The
(Register 17-1) 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.
The block diagram for the HLVD module is shown in
Figure 17-1.
