PIC18F47J53 FAMILY
26.1
When the HLVD module is enabled, a comparator uses
an internally generated reference voltage as the set
point. The set point is compared with the trip point,
where each node in the resistor divider represents a
trip point voltage. The “trip point” voltage is the voltage
level at which the device detects a high or low-voltage
event, depending on the configuration of the module.
When the supply voltage is equal to the trip point, the
voltage tapped off of the resistor array is equal to the
internal reference voltage generated by the voltage
reference module. The comparator then generates an
interrupt signal by setting the HLVDIF bit.

Preliminary
HLVDL<3:0>
The trip point voltage is software programmable to any
one of 16 values. The trip point is selected by
programming the HLVDL<3:0> bits (HLVDCON<3:0>).
Additionally, the HLVD module allows the user to
supply the trip voltage to the module from an external
source. This mode is enabled when bits, HLVDL<3:0>,
are set to ‘1111’. In this state, the comparator input is
multiplexed from the external input pin, HLVDIN. This
gives users flexibility because it allows them to
configure the HLVD interrupt to occur at any voltage in
the valid operating range.
