Hello !


I can see in all examples in SDK is only FLASHTIM is set .


But what about enable flash prefetch and acceleration bits ?

They never enabled. Why ? They should work with silicon 1B.


How to handle those ?

Can I enable those at the same time when FLASHTIM is changed ?


Should I invalidate/flush those caches when use Flash API from Bootrom ?

Or when I encrypt/decrypt on fly if PRINCE peripheral is in use.


In K82 time it was always separate API to handle those issues.
