22.0
PIC18F2XK20/4XK20 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 inter-
rupt vector address and the software can then respond
to the interrupt.
The
(Register 22-1) 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 22-1.
The module is enabled by setting the HLVDEN bit.
Each time that the HLVD module is enabled, the cir-
cuitry requires some time to stabilize. The IRVST bit is
a read-only bit and is used to indicate when the circuit
is stable. The module can only generate an interrupt
after the circuit is stable and IRVST is set.
The VDIRMAG bit determines the overall operation of
the module. When VDIRMAG is cleared, the module
monitors for drops in V
point. When the bit is set, the module monitors for rises
in V
