To operate the driver in this configuration, the registers should be loaded with the values in Table 19-16.
The voltage generator has to be configured for the use of the internal reference (VgenRefEn=1 in RegVgenCfg0).
The generator has to run (VgenOff=0 and VgenStdb=0 in RegVgenCfg0). It has to generate 1/3 bias
(VgenMode=0 in RegVgenCfg0) and the generator output impedance is set to minimum (VgenClkSel=11 in
RegVgenCfg0).
The LCD driver is set to 1:4 multiplexing (LcdMux=11 in RegLcdOn) and the waveform generator is enabled
(LcdSleep=0 in RegLcdOn). All pads are set into the LCD driver mode by setting all bits of register RegLcdSe to
