AD4696 - register read not working after converions mode

Product Number: AD4696


I am using 2 AD4696 sharing intput signals (CNV, CS/, SDI and Reset/).

Configuration register phase is OK. I can set any register and read them back. I am using  standard sequencer for conversion mode.

I can change to converison mode and read values on SDO are correct.

When I try to go back to configuration mode, I send the register configuration mode command (0x0A) on SDI. tRECONFIG time is respected.

Change mode seems to be OK as I am not getting anything more on SDOs.

But when I try to read any register I get 0xFF.

Any idea what I am doing wrong ?
