we have an ADAU1701 controlled by a Coldfire µC over SPI.
This usually works fine but in some cases the communication fails.
We started development of a first device with ADAU1701 with SPI mode 0 (CPOL=0, CPHA=0) and it worked (ARM µC, no OS).
We did a second design (Coldfire, Linux) and had problems with that setting.
Searching in the forum I found out that BrettG recommended SPI mode 3 (CPOL=1, CPHA=1).
We tested that mode but here it never worked.
We tested CPOL=0, CPHA=1 and also get some random fails.
Can someone confirm the correct SPI mode for the ADAU1701?
