Re: A89: interrupts
shouldn't auto int 5, with oscillator set to 22kHz (bit 5 and 4 in $600015
cleared) and initial value of counter to $FF or something to make it trigger
every other increment ( I think that is the most you could set it to), be more
suitable?
Then you have an interrupt running at 11kHz instead of auto-int 1:s original
~350Hz, or 5.5kHz as most.
I havn't done any multitasking stuff myself, but my intuitive feeling says that
350Hz is a bit slow.. maybe even 5.5kHz is a bit much, and then it is better
to use auto int 5, wich you can modify more exact.
