KA10: Fix MTY bug #224

Closed larsbrinkhoff closed 3 years ago

larsbrinkhoff commented 3 years ago

MTY input and output will sometimes be garbled. I confirmed that logging DATAIO will display input on a line that I know is idle.

When I studied the code I see that both mty_input_svc and mty_output_svc can write the MTY_LINE bits in the status register. I believe the fix should be to sim_cancel both svcs when an interrupt is posted. I will test this and post a pull request soon.

Please hold off on a pull request until I do my next pull to the repo.
