14.5. System interface

The system interface is a 32-bit AHB-Lite bus. Instruction and vector fetches, and data and debug accesses to the System memory space, 0x20000000 - 0xDFFFFFFF, 0xE0100000 - 0xFFFFFFFF, are performed over this bus.

For simultaneous accesses to this bus, the arbitration order in decreasing priority is:

The System bus interface contains control logic to handle unaligned accesses, FPB remapped accesses, bit-band accesses, and pipelined instruction fetches.
