We just can not figure out which SPI mode to select. I am a bit confused about the information in the Data Sheet. Figure 2 and Figure 4 are differing a bit in the timing. Also the Pin PIN DESCRIPTIONS AND EQUIVALENT CIRCUITS table I do not understand. Reading the text for DOUT and DIN I would assume that the SPI mode differs for both. Can this be true!? Most probably I have overseen something.
In the end can you tell which SPI mode has to be used here?
