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
