Instr.
Each Slave has its own arbiter, thus allowing a different arbitration per Slave to be programmed.
Table 6-2.
All the Masters can normally access all the Slaves. However, some paths do not make sense,
such as allowing access from the Ethernet MAC to the internal peripherals. Thus, these paths
are forbidden or simply not wired, and shown “-” in the following tables.
