* The ADC channels have a fixed mapping:
*
* | Channel | MCU Pin | Arduino pin on board |
* |:---------- |:--------- |:------------------------------------- |
* | AIN0 | P0.26 | -- (exposed, by no Arduino UNO pin) |
* | AIN1 | P0.27 | -- (exposed, by no Arduino UNO pin) |
* | AIN2 | P0.01 | A0 |
* | AIN3 | P0.02 | A1 |
* | AIN4 | P0.03 | A2 |
* | AIN5 | P0.04 | A3 |
* | AIN6 | P0.05 | A4 |
* | AIN7 | P0.06 | A5 |
*
* Expose those on Arduino pins A0 to A5
