PIC18F1220/1320
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,
