Thread: Multiple IRQ'S ?
face BY : Kbek Tony email (remove spam text)

What's the 'best' way to interface several external irq requests ?
PortB change feature seems 'no-go', OR'ing several irq's
to the INT pin seems doable ( and then poll which one it was )
but potentially dangerous ( strong possibility of missing one ).

Any suggestions ?
