If we use the Arm Architecture as a reference, we can form a mapping between the instructions executed, and the transactions that might be issued on the interface. WebA Cache Maintenance Operation flushes or invalidates a cache line from the coherency domain. This can allow interaction with non-coherent devices that access the slave directly. Since a Last Level Cache can hold additional data, it may be necessary to flush or invalidate lines from the LLC to memory. When this register bit is set, the CCC will ...
