The R5FSS has several initiator interfaces per
core:
- 64-bit VBUSM initiator pair (1 read – “RMST”, 1 write – “WMST”) for L3 memory
accesses; this is the main memory interface
- Includes region-based
address translation (RAT)
- 32-bit VBUSP initiator “PMST” for peripheral access
- Includes logic that
provides the R5F CPU with a private access to VIM and RAT
- Enabled at reset
