Peripheral DMA Controller
SAM9260
Table 7-3.
The Peripheral DMA Controller handles transfer requests from the channel according to the fol-
lowing priorities (Low to High priorities):
• Acting as one Matrix Master
• Allows data transfers from/to peripheral to/from any memory space without any intervention
• Next Pointer Support, forbids strong real-time constraints on buffer management.
• Twenty-two channels
