Hi Mark,
When debugging  on register caching, found that register is getting 
cached only when write happen to the register otherwise it will not get 
cached even any number of read happen.
Is it by intended or there is opportunity to enhance it so that during 
read also we can cache it.\?

Thanks,
Laxman
