I am inclined to say you can not use the Arduino SPI library. Instead, you may need to bit-bang this out totally in software. For instance, I do not believe there is a "SYN" line in the standard SPI bus. And I don't believe the Chip Select line should go high before the end of the SPI transaction. | |

There is a timing diagram to switch from read only and write only. My problems is to how to read the data from the registers of the chip. I used SPI.transfer but I don't think the data is reliable. | |
