I played a bit in the direction of running a program via IRQ only: some settings at the beginning that pass to IRQ all the job.
It means that all the code runs at IRQ timing, after the initial code, and this initial code must start the IRQ waterfall.
In order to do it, the setup code must finish with a RTI, or a BRK, or a nested JSR, and playing with stack and counter in order to make it works.
I tried lotta choices, but no one, had worked.
Hence: which's the secret within? |
