FIGURE 21-2:
The LVD module has an additional feature that allows
the user to supply the sense voltage to the module
from an external source. This mode is enabled when
bits LVDL3:LVDL0 are set to ‘1111’. In this state, the
comparator input is multiplexed from the external input

pin, LVDIN (Figure 21-3). This gives users flexibility,
because it allows them to configure the Low-Voltage
Detect interrupt to occur at any voltage in the valid
operating range.
