2.5. Exclusive monitor

The Cortex-M7 processor implements a local exclusive monitor. For more information about semaphores and the local exclusive monitor see the Arm®v7-M Architecture Reference Manual.

The local monitor within the processor is constructed so that it does not hold any physical address. Instead it treats any access as matching the address of the previous LDREX instruction. This means that the implemented Exclusives Reservation Granule (ERG) is the entire memory address range.
