Ok, I've read, re-read and re-re-read the ..very.. confusing documentation for the Kinetis K60P144M120 ADC.
It seems to me that you can use the DM3 / DM0 pin input as a single ended input,
Given you set ADC SC1[n] ADCH to %11010.. (and that you have PGA0 up?), you should get DM0/DM3..
In the data sheet ADCH = %11010 shows a note that it is DM0 - interlaced with DM3. How do I specifically select DM0 or DM3..?
Anyone? Am I missing something? Help?
