AT91SAM9X25 Master to Slave Access
SMD
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 the following table.
