AD7280 support!

I'm using the AD7280 Li-Ion monitor IC. I control it with a BF506 (SPI). The SPI clock is set to 100kHz to not exceed the maximum clock speed (1MHz).

The Problem i have is that no useful data is sent back from the AD7280. I'm not sure about the communication to the AD7280. Can I use 8bit or 16bit SPI communication? The 32bit frame I have to send (e.g. OverVoltage register read) is correct as i compared it to some example frames shown in the datasheet.


Anyone knwoing some details regarding the AD7280 communication?


thanks in advance!
