The debug access bridge arbitrates and connects one set of read and write ports from a CPU to the MEMSS memory controller using static select arbitration as described in Section 3.10.6. This is common to the entire system. Arbitration and security access filtering can take up to two cycles, and debug accesses through this bridge are a two wait state minimum.
The initiator select connects one of the CPU buses to a common debug port, so the output buses cannot have accesses from more than one initiator at a given time. Debug read and write accesses identified as illegal are blocked in the debug access bridge.
Common debug access ports have a CPU-ID to indicate the origin of the current access. This ID can be used to implement access filtering, if needed. Following are the CPU-ID assignments:
The two types of memory regions have access filter handling :
