   5 Description:
   6                 Get measured values from the ADC for these stages. Y is the
   7                 specific stage number corresponding to datasheet stage names
   8                 as follows:
   9                 1 -> LED2
  10                 2 -> ALED2/LED3
  11                 3 -> LED1
  12                 4 -> ALED1/LED4
  13                 Note that channels 5 and 6 represent LED2-ALED2 and LED1-ALED1
  14                 respectively which simply helper channels containing the
  15                 calculated difference in the value of stage 1 - 2 and 3 - 4.
  16                 The values are expressed in 24-bit twos complement.

  22 Description:
  23                 Get and set the offset cancellation DAC setting for these
  24                 stages. The values are expressed in 5-bit sign-magnitude.
