21.2.1
The Internal Reference Voltage of the LVD module may
be used by other internal circuitry (the programmable
Brown-out Reset). If these circuits are disabled (lower
current consumption), the reference voltage circuit
requires time to become stable before a low voltage
condition can be reliably detected. This time is invariant
of system clock speed. This start-up time is specified in
electrical specification parameter #36. The low voltage
interrupt flag will not be enabled until a stable reference
voltage is reached. Refer to the waveform in
Figure 21-3.
21.2.2
When the module is enabled, the LVD comparator and
voltage divider are enabled and will consume static cur-
rent. The voltage divider can be tapped from multiple
places in the resistor array. Total current consumption,
when enabled, is specified in electrical specification
parameter #D022B.
21.3
The LVD module has an additional feature that allows
the user to supply the trip point voltage to the module
from an external source (the LVDIN pin). The LVDIN pin
is used as the trip point when the LVDL3:LVDL0 bits =
’1111’. This state connects the LVDIN pin voltage to
the comparator. The other comparator input is con-
nected to an internal reference voltage source.

Advanced Information
21.4
When enabled, the LVD circuitry continues to operate
during SLEEP. If the device voltage crosses the trip
point, the LVDIF bit will be set and the device will wake-
up from SLEEP. Device execution will continue from
the interrupt vector address if interrupts have been glo-
bally enabled.
21.5
A device RESET forces all registers to their RESET
state. This forces the LVD module to be turned off.
