P10, P11: do not use P14, P13, P12: CL dividing ratio. They are used to change number of dividing stages of external or internal clock. P14 P13 P12 CL dividing ratio 0 0 0 0 0 1 0 1 0 0 1 1 Not divide 2 divisions Not divide Not divide P2: It is used to specify the duty of the module on block basis. Duty * * P25 P24 P23 P22 P21 P20 (Numbers of display lines)/4-1 Example: 1/128 duty 0 0 0 1 1 1 1 1 128/4-1=31 P3: It is used to specify number of lines to be inversely highlighted on LCD panel from P33 to P30 (lines can be inversely highlighted in the range of 2 to 16) Inversely highlighted line * * * P34 P33 P32 P31 P30 Inversely highlighted lines-1 Example: 11H 0 0 0 0 1 0 1 0 11-1=10 Example: 13H 0 0 0 1 1 1 0 0 13-1=12 In the default, 11H inverse highlight is selected. P34= ”0”: Inversion occur every frame. P34=”1”: Independent from frames.
