PNEV512B Can't turn on Analog part of the receiver

I am using a PNEV512B Board over SPI. 
I connected following pins: IRQ, NRST, SSEL, SCK, MISO, MOSI, GND and a USB power cable. 

My SPI is working. (I verified it by testing the fifo, interrupts and reading the inital values of the registers.)


Now my problem is, if I am trying to run the self test it fails with no bytes in fifo buffer at the end. I read a thread where someone had the same problem because he forgot to turn on the analog part of the PN512.

So i was trying to set RcvOff in the command register to zero, but I am not able to do this. It simply sticks to 1.


Can anyone give me a hint what I probably have missed? Are there maybe any configurations to do before setting this bit to zero?


Thanks in advice.
