# Not able to set a value into an ADC

I'm trying to configure an ADC (ADC12j4000) and I need to configure the number of serial lanes (denoted as L in the page 39 of the datasheet). For some factors as D, DDR, P54, K... I can see how to configure them in the page 70 of the datasheet, where by some address, I can configure the ADC for the desired values. But as I mentioned before, I am not able to configure the number of lanes. Is there any other way to do it?

Any help is appreciated! Thanks for all!
