The LCD module can be configured for one of three
bias types:
• Static Bias (2 voltage levels: V
• 1/2 Bias (3 voltage levels: V
• 1/3 Bias (4 voltage levels: V

TABLE 26-2:
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
to Figure 26-3.
