Which Registers control SPI Mode and other configuration?
The datasheet warns that "The master port must be reconfigured in software before using a protocol other than the one configured at boot time." So, how is this done? Which Registers control this confi

Audio Delay versus Sample Rate
When operating the ADAU 1701 with double to fourfold sample rate the audio delay (analoge input to analog output) is not 1/2 or 1/4 compared to 48 kSps as expected. I measure 1/3 and 1/9 compared to 4
