Hi @PatrickB ,
As of now, there is no such particular parameter to tell XMC do not wait for acknowledge. However, in case you want to implement I2C without acknowledge, just keep sending data from the master. You do not need to wait for the acknowledge in the while loop. This should work.
Also, as per the I2C specification, I2C slave is supposed to provide an ACK so as to let the master know that the transfer is complete. But in case you want to avoid that, please try the above given action.
