FPDlink3 i2c Pass Through and Pass all DS90UB913/4 DS90UB925/926

Hello Everybody,


In our project we use very often TI fpdlink3 serdes chips, in these days we stumbled into the 913/914 couple.

Seems to me that the logic of the pass through and the pass all is very different from the 925/926 couple or the other 92x series (despite the description in the data sheets being the same).

After enabling the pass all option on the 913 we got all the addresses of the i2c bus ACKed by the remote 914 deseriazlier whitout any remote slave present... what's the purpose of this behavior?

How can we set the pass-all function to access remote slaves without having to set slave aliases?

Thanks a lot,

Marco
