I2C ISR - MC9S12DP512

[IgorN]

I'm using  the I2C-block of MC9S12DP512 in slave mode only.

Did I need to handle the Arbitration Lost in this case?

Added p/n to subject.

Thanks, but one think is not clear for me yet.

Did the "arbitration lost" interrupt can to appear if my unit is constantly slave on I2C bus.

I'm undestend from the DS & AN that this interrupt couse if the unit in master mode.

Since if my unit is constantly slave(never master) did I must to handle this interrupt in the interrupt service routine?

Hello,

The arbitration lost feature would usually only be applicable to a multi-master configuration, so that a master may be changed to slave mode, when another master has access to the IIC bus.
