+Description:
+ Get measured values from the ADC for these stages. Y is the
+ specific stage number corresponding to datasheet stage names
+ as follows:
+
+ == ==========
+ 1 LED2
+ 2 ALED2/LED3
+ 3 LED1
+ 4 ALED1/LED4
+ == ==========
+
+ Note that channels 5 and 6 represent LED2-ALED2 and LED1-ALED1
+ respectively which simply helper channels containing the
+ calculated difference in the value of stage 1 - 2 and 3 - 4.
+ The values are expressed in 24-bit twos complement.
+ The LED current for the stage is controlled via
+ out_currentY_raw.
