Figure 19-20 and Table 19-27 show a possible example for such a configuration. In this case, the LCD driver
voltage V3=VBAT and V1=VBAT/2 (1/2 bias mode, VgenMode=1, VgenRefEn=0 and VgenOff=0 in
RegVgenCfg0). The LCD is in 1:2 multplexing (LcdMux=01 in RegLcdOn) and LcdSe19=LcdSe23=1 while all
other bits in RegLcdSe are 0.
