The AHB-AP provides the following specific MEM-AP features:
auto-incrementing of the Transfer Address Register with address wrapping on 1K byte boundaries
word, half-word and byte accesses to devices present on the AHB memory system
packed transfers on sub-word transfers.
The AHB-AP does not support the following MEM-AP features:
Big-endian. All accesses performed as expected to be to a little-endian memory structure.
Slave memory port disabling. The AHB-Lite master interface is not shared with any other connection so there is no slave port to disable access to this interface. If the memory-map presented to the AHB-AP is to be shared with another AHB-Lite master then this is implemented externally to the DAP.
