the Digital Interface Format and the options are detailed in Figures 11-13.
6.5.2 ADC ONE_LINE MODE (ADC_OLX)
Default = 00
Function:
These bits select which mode the ADC will use. By default, One-Line Mode is disabled, but it can be
selected using these bits. Please see Figures 14 and 15 to see the format of One-Line Mode 1 and
One-Line Mode 2.
