PIC18F6310/6410/8310/8410
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 inter-
rupt 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.

HLVDL<3:0> modes that result in a trip point, below the valid operating voltage of the device, are not
tested.
VDIRMAG: Voltage Direction Magnitude Select bit
1 = Event occurs when voltage equals or exceeds trip point (HLVDL<3:0>)
0 = Event occurs when voltage equals or falls below trip point (HLVDL<3:0>)
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 range
0 = Indicates that the voltage detect logic will not generate the interrupt flag at the specified voltage
