The Bus Matrix of the SAM3U manages 10 slaves. Each slave has its own arbiter, allowing a dif-
ferent 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 Device High speed DMA to the Internal Peripherals.
Thus, these paths are forbidden or simply not wired, and shown as “–” in
