ADAU 1701 datasheet REV B. Page 32, Table 31. First group.
Address 0x0800 through 0x0807 Interface registers are all called out as "interface 0"
Shouldn't they be called out as interface zero through interface seven??
You are correct. The ADAU1701 datasheet incorrectly names all of these registers as Interface Register 0.
The problem appears to be fixed in the more recent ADAU1401A datasheet:
I will add this to the list of edits for a revision C ADAU1701 datasheet.
I moved this question about the ADAU1701 to the SigmaDSP Community. Someone here will be able to help with this.
