TABLE 27-2:
So that the user is not forced to place external compo-
nents and use up to three pins for bias voltage generation,
internal contrast control and an internal reference ladder
are provided internally to the PIC16F/LF1946/47. Both of
these features may be used in conjunction with the exter-
nal VLCD<3:1> pins, to provide maximum flexibility. Refer
