Is this true? I can believe it to be. If so, is there any way I can replace this functionality using the interrupt driven counters or something? A hardware counter is not an option unfortunately, as the board is already in units in the field.

The reason I need to add interrupts is because I need to add background hardware UART character reception using UART2 because the program spends too much time doing other things in the foreground to service the port soon enough.

Is there a list of what PBP functions are affected by DT_INTS? If so where can I find it?

Does anyone have examples of interrupt driven serial IO using DT_INTS? How about pulse counting routines?

Thanks,
Mike
