The address tenure for PCR synchronization operations is redefined to support inclusion of the synchronization data within the address tenure. The bits of a particular field within the address tenure (e.g., the address field) are re-allocated to synchronization data, which is known to be small enough to fit within the unused bits. The address tenure is then broadcasted as a normal address operation and is snooped by all of the processors. The snooping logic is designed to recognize regular/normal address tenures and these modified address tenures and respond to a receipt of a modified address tenure by removing the synchronization data stored therein and updating the corresponding register location of the PCR.
