Using DM3 as a single ended ADC input on K60 ..?

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?

This should help you understand what the "interleaved" means:

For every ADC it only matters what you set in ADCH and whether you use differential measurement or not.
