Just because of interest:
the program mask was set by the ESPIE macro, according to the
interrupts you wanted to be caught by the ESPIE routine, and it had
nothing to do with the ATTACH macro, which attached the subtask;
am I correct? So it is in fact an ESPIE topic, not related to subtasking?
And not related to LE?
Do you know, if ATTACH does anything to the program mask, or is
the program mask for the subtasks simply inherited from the master task?
Hi Bernd!
*VERY* good points! Many thanks for asking.
And - yes - you are correct, the mask was being set by the ESPIE macro
(in a reasoning I imagine is close to what you have described above.) It
had nothing to do with the ATTACH macro. The sub-task clearly got
the same program mask as the parent task (I don't know if that is by
design or they both just happened to be initially set to the same value.)
So, yes, it is related to ESPIE and not subtasking.
And, also not at all related to LE (you can imagine we don't do too
much LE.)
I'm not aware if ATTACH does anything with the mask. I would assume it
inherits the mask from the parent, but I don't actually know the answer
to that.
