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
+
+ == ==========
+ 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.
