Different duties require different bias settings. There is some reference correspondence between the Duty
and Bias Setting. However, it is better to use it as starting point and adjust it with real LCD panel
connected to it to determine the final setting. The relationship between the duty and bias setting is just for
reference as following:
Duty Cycle Normal Bias Alternative Bias
32 duty
1/7
1/7.5
48 duty
1/8
1/7.5, 1/8.5
64 duty
1/9
1/8.5, 1/9.5
The bias setting is made by mask option MO_LBSR[3..0].
