Thread: Interrupt Questions

Hi Three,

You can still read the pin even if it's set up to be an interrupt.

As far as using a goto instead of a retfie, any path you take must
eventually end in retfie or you'll break the stack. And since you ask
the question, let me suggest that by asking that particular question I
think the structure of your program is faulty if you are thinking about
doing it that way. Interrupts should be fairly short, maybe increment a
counter, put a byte in a buffer, or set a flag and then return.

Cheerful regards,
