Hello, Conor! I really appreciate the feedback!

The way I thought about it, the only thing constraining the number of 
channels is the reg number (minimum: 0, maximum: 271). 272 channels 
cover all possible combinations (16*16 differential and 16 single ended) 
and I thought there is no need for anything stricter. I added items: 
minimum:1 maximum:16 to make sure the numbers are from 1 to 16, 
corresponding to AIN1-AIN16.

Please let me know what should be improved!

Kind regards,
Alisa-Dariana Roman.
