The R5FSS has several target interfaces that define its internal memory space:
Regions [0] and [1] of the TCM target interface provide direct access to the TCM RAMs. Access to the RAMs is arbitrated with access from the R5F’s L1 memory system. Excessive access while the R5F is also attempting access will degrade performance.
Regions [2] and [3] of the TCM target interface provide access to the cache RAMs for testing purposes. Access to the cache RAMs can only be done while the caches are disabled and should only be done for test purposes.
In addition to the target interfaces, there are peripherals (RAT and VIM) that are only accessible by the R5F. The R5F has an access to these modules via the VBUSP peripheral interface.
