If we are in the cacheable region and cache is activated, we must clean D$ (if Cache Coherency Attribute is set to 3) + invalidate I$ after we did the write, so that changes do not continue to live only in D$ (if CCA = 3), but to be replicated in I$ also (maybe we wrote the instructions)

Check cacheability bits coherency algorithm is the region cacheable or uncached. If cacheable we have to synchronize the cache
