Register compatibility ADAU1452 <> ADAU1462 ?!

JoergS on Nov 3, 2020

Though it is said the two mentioned parts are 100% SW and register compatible their spec says something different:

Is the ADAU1462 spec correct?

Thanks

In fact they are not identical, one say locked bit value (0) zero, another say locked value (1) one. so they are inverted on value, but bit order is the same, also i do not have both DSPs to check if is…

I would be glad to answer, as I'm going to use both the 1452 and 1462 for their pin compatibility; but I don't have both devices here for testing at the moment, only the 1452.

Also, by looking closer at the images you shared, I don't see the difference.
Those registers look 100% identical.

Nice catch!
So everybody here have a 1452 right? We just need one tester with a 1462... :/
