TLB Refill and TLB Invalid Exceptions on CacheOps
TLB Refill and TLB Invalid exceptions can occur on any operation. For Index operations, where the address (virtual address for the primary caches, physical address for the secondary cache) is used to index the cache but need not match the cache tag, unmapped addresses may be used to avoid TLB exceptions. The operation never causes TLB Modified exceptions.
