11.7. AHB-AP

AHB-AP is a debug access port into the Cortex-M3 system, and provides access to all memory and registers in the system, including processor registers through the NVIC. System access is independent of the processor status. Either SW-DP or SWJ-DP accesses AHB-AP.

AHB-AP is a master into the Bus Matrix. Transactions are made using the AHB-AP programmer’s model, which generates AHB-Lite transactions into the Bus Matrix. See Summary and description of the AHB-AP registers.
