Hi,I looks like the NS9750 I2C master does not decouple from bus when it looses Arbitration during address phase. Instead it pulls the SCL line to low forever. So I can not handle the M_ARBIT_LOST irq like described in the Flow chart in the User manual. What is the recommended way to handle arbitration loss ? Jochen
I found no other way to get back control over the I2C Bus than resetting the I2C-Controller completely. Unfortunately a reset also resets the slave statemachine. This makes it complicated to use the NS9750 as I2C master and slave at the same time, but it is possible. Jochen
