OSEL | Output Amplitude Type | ||||||||
This bit selects the output amplitude type. The clock autoset feature will not work with PLL enabled in VCOM mode. In this case this feature has to be disabled via Page 0 / Register 37 and the clock dividers must be set manually. | |||||||||
Default value: 0 | |||||||||
0: VREF mode (Constant output amplitude against AVDD variation) | |||||||||
1: VCOM mode (Output amplitude is proportional to AVDD variation) |
