FIGURE 18-2:
The LVD module has an additional feature that allows
the user to supply the trip voltage to the module from
an external source. This mode is enabled when bits
LVDL3:LVDL0 are set to 1111. In this state, the com-
parator input is multiplexed from the external input pin,

because it allows them to configure the Low Voltage
Detect interrupt to occur at any voltage in the valid
operating range.
