6.5.5.6.3 Memory Access Port

Essentially, a MEM-AP is a bus host on a bus interface. It is accessed and controlled by reading and writing to its register interface using the DP. Any memory-mapped resource that is accessible from the bus driven by this MEM-AP can be written or read from, following the normal access permissions of that resource.

The devices in the PIC32CM PL10 family contain one MEM-AP, which is an AHB-AP.

The AHB-AP connects through the CPU’s AP and to the AHB bus matrix. The MEM-AP can access all subsystem memory-mapped resources in the design. The only exception to this is when the device is protected (DAL < 0x2); in this case, the DSU performs security filtering as described in the Debugger Security section.
