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 PIC16F193X/LF193X. Both
of these features may be used in conjunction with the
external VLCD<3:1> pins, to provide maximum flexibility.
Refer to Figure 26-3.
