Hello Aejaz,
Are you trying to reproduce the register corruption?
If so, you would need to do power loss during the WRR. If you try enough times, you should be able to see it.
Thank you

Hi Bushra,
Thanks for your feedback. we're trying as per the KBA sudden power loss application note . We made some changes and adjust the "WRR Write Time" Typ.140msec & Max.500msec as mentioned in datasheet but still we're enable to reproduce the phenomenon. do you have any idea how we can reproduce it.
Thanks
Best Regards,
