    I want to introduce delays in both channels of the ADC. For this I use the registers 0x0110, 0x0111 and 0x0112. On channel A, this works perfectly, but on channel B, it does not work. The order that I follow in the record configuration for channel B is as follows:
    
 
    - 0x0564 -> 0x01 (Change to channel B as output).
    - 0x0110 -> 0x06 (Active fine delay and super fine delay).
    - 0x0112 -> 0x0F (I enter a delay. This value is irrelevant).
    
 
    Am I missing any additional records for this to work on channel B? Am I doing something wrong?
    
 
    Thank you so much.
    
 
    Best Regards.

        Hi Umesh,
        
 
        Previously the index register (0x0008) did not change and therefore it did not work. Now I change that register but I notice that the value is not changed, and therefore I still did not manage to change the delay in channel B, why should it be that I can not update that record?
        
 
        Thank you so much.
