The BitsyXb manual lists 3 external intrs on J10. The DIO spec doesn't list any digital I/Os (it doesn't list the BitsyXb at all). Where can I find the DIO maps and information on using the external interrupts on the Xb?
I took a look at the BitsyXb DIO driver, and it maps the EIO pins (found on J3 and J10) in the same manner as the BitsyX (the BitsyXb LED is not currently mapped in the DIO driver). All ten EIO pins on the BitsyXb are interrupt-capable. You can query the driver directly to confirm these capabilities.
