Preliminary data sheet
6.13 Multi-layer AHB
The following blocks can generate interrupts:
The multi-layer AHB is an interconnection scheme based on the AHB protocol that
enables parallel access paths between multiple masters and slaves in a system.
Multiple masters can have access to different slaves at the same time.
Figure 5
AHB masters and slaves are numbered according to their AHB port number.
