SAM3X/A Series Master to Slave Access
The Bus Matrix of the SAM3X/A series product manages 9 slaves. Each slave has its own arbi-
ter, allowing a different arbitration per slave.
Table 7-2.
All the Masters can normally access all the Slaves. However, some paths do not make sense,
for example allowing access from the USB High Speed DMA to the Internal Peripherals. Thus,
these paths are forbidden or simply not wired, and shown as “-” in the following table.
