22.2.1
The internal reference voltage of the LVD module,
specified in electrical specification parameter #D423,
may be used by other internal circuitry (the Program-
mable Brown-out Reset). If these circuits are disabled
(lower current consumption), the reference voltage
circuit requires a 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 22-4.
22.2.2
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.

22.3
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 globally enabled.
22.4
A device Reset forces all registers to their Reset state.
This forces the LVD module to be turned off.
