FIGURE 23-2:
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
LVDIN to one input of the comparator (Figure 23-3).

The other input is connected to the internally generated
voltage reference (parameter #D423 in Section 27.2
“DC Characteristics”). 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.
