L9963E response frame error

Dear community member,

I am using L9963E IC on custom pcb board. I send a command to read register address 0x02 of device 1, but in response frame getting address feedback for register address 0x06. 

also while reading dev_gen_cfg, getting different response if reading it twice.

I had changed the spc example code to run on STM32G4, and keep bne polling to read response by dending 0x55 0x55 0x55 0x55 0x55.

what could be the possible cause for 1 added extra bit in address feedback section of response frame ?

Thanks
