The R5FSS has several initiator interfaces:
- 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
