DAC43608: Read back DAC register not working

Part Number: DAC43608

Hello,

we are using the DAC43608 in our application. Everything works fine except for read back of the DAC values.
Read back of configuration and status register is working. When I try to read the registers 8-15 I always get
0x0000 as results no matter what was written before.

Writing definitively works. The DAC outputs are changing according the written values.

What I am doing wrong?

A SW reset is done before using the DAC. LDAC input is not used and set permanently to low.

Thanks and regards

Guenter
