On my (noisy) system, I2C arbitration losses happen quite often. In it's
current implementation, the IAL flag is partly handled, but has a
number of shortcomings:
1. The driver runs unnecessarily in a timeout when waiting for an
interrupt.
2. The driver performs 500 ms busy-waiting without any value.
3. Arbitration loss errors may be reported one transfer later than they
occured.
Best regards
Christian
