AT91SAM9XE128/256/512 Preliminary
7.2.3
Masters to Slaves Access
All the Masters can normally access all the Slaves. However, some paths do not make sense,
such as allowing access from the Ethernet MAC to the internal peripherals.
Thus, these paths are forbidden or simply not wired, and shown as “–” in the following table.
7.3
Peripheral DMA Controller
Acting as one Matrix Master
Allows data transfers from/to peripheral to/from any memory space without any intervention
of the processor.
Next Pointer Support, forbids strong real-time constraints on buffer management.
Twenty-four channels
– Two for each USART
– Two for the Debug Unit
– Two for each Serial Synchronous Controller
– Two for each Serial Peripheral Interface
– Two for the Two Wire Interface
– One for Multimedia Card Interface
– One for Analog To Digital Converter
The Peripheral DMA Controller handles transfer requests from the channel according to the fol-
lowing priorities (Low to High priorities):
– TWI0 Transmit Channel
– TWI1 Transmit Channel
– DBGU Transmit Channel
– USART4 Transmit Channel
– USART3 Transmit Channel
