We need a 1ms delay and are just testing the CYGACC_CALL_IF_DELAY_US - it
seems this will solve our problem.

Thanks a lot for the help

How short?  If it's truly short, you could use CYGACC_CALL_IF_DELAY_US

Otherwise, you'll need to set up some sort of high[er] resolution clock
[timer] and use that (which, depending on your hardware, might be messy)
