I have  multiple ADAU442 in my system and recently added a rms and readback block so I could read the rms value of a signal ,Anyhow, when I first read the register I get normal  reading the seem reasonable. However, when I read the register a second time I get all 0xffs. 3rd time is fine 4th is 0xff etc. Is this normal behavior?
