That is so true ...

But so far, I haven't found a possible reason for anyone to have Low Priority interrupts, without High Priority.
Consequently, DT_INTS crashes if you try to only use LP ints, mainly because I haven't seen the need.

Is there a reason anyone can think of for using only Low Priority Interrupts?
Enquiring minds want to know.
