I took some time to read through the i.MX RT1060 reference manual chapter on the four Analog comparators (ACMP1, ACMP2, ACMP3, ACMP4) which are built in to the processor. (Note these comparators are different from the two ADCs). The nice thing is each of the four comparator's output pin is accessible via teensy pins A14, A15, A12, A13 (respectively). And there are multiple options for input pins, most of which are accessible too. It took me a couple hours to go through the reference manual to figure this out, so I'm sharing the mapping with anyone here that might find this info useful:
and here is the spreadsheet I made that mapping with: https://docs.google.com/spreadsheets/d/1RmWodjGw5-zTuVWB8b3224ZehmVzOBJYnmfSyLFC2cs/edit?usp=sharing
