The Cortex®‑M33 processor implements a local exclusive monitor. The local monitor within the processor has been constructed so that it does not hold any physical address, but instead treats any store-exclusive access as matching the address of the previous load-exclusive. This means that the implemented exclusives reservation granule is the entire memory address range.
For more information about semaphores and the local exclusive monitor, see the Armv7‑M Architecture Reference Manual.
