PIC18F6390/6490/8390/8490
High/Low-Voltage Detect module (HLVD). This is a pro-
grammable 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

HLVD module. This allows the circuitry to be “turned
off” by the user under software control, which
minimizes the current consumption for the device.
