5.1.2. Functional interfaces

The APB interconnect with the ROM table has a configurable number of AMBA 3 APB-compliant slave interfaces and AMBA 3 APB-compliant master interfaces. Each master interface can address a configurable address size, to support CoreSight components that require more than 4KB of address space. The base address of each master must align to its size.

The DbgSwEnable bit in the APB-AP can be used to prevent self-hosted, on-chip, accesses.
