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.
