  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. == ==========
  10. 1 LED2
  11. 2 ALED2/LED3
  12. 3 LED1
  13. 4 ALED1/LED4
  14. == ==========
  15. Note that channels 5 and 6 represent LED2-ALED2 and LED1-ALED1
  16. respectively which simply helper channels containing the
  17. calculated difference in the value of stage 1 - 2 and 3 - 4.
  18. The values are expressed in 24-bit twos complement.
