    It seems definitly that I am not able to make the slave mode working on PSD3234A.

    I made a lot of tests including: interrupt mode, no interrupt, various bus speed, and always the same result: SCL low after own address recognition, and no way to exit this.

    Does anybody have an idea to overcome this ?

    It seems to be that in order to exit the wait condition after receiving own addresse in slave mode, a dummy write in SxDAT register should be done.
