After writing registers you can simply read the registers. Then you know the real content of the register.

Hello @M Prasanth, definitely the most easiest way is mentioned by @chr_sue. Another way (not much recommended) can be if you know the design probe, you can try backdoor read. Depending on your usage, meaning if you've to do 100 writes and then reads, it may take time but backdoor can be faster. But then you might be missing to check the read functionality of register.
