SAM9260 [SUMMARY]
6221LS–ATARM–15-Oct-12
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-two channels
Two for each USART
Two for the Debug Unit
Two for each Serial Synchronous Controller
Two for each Serial Peripheral 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 following priorities (Low to
High priorities):
DBGU Transmit Channel
USART5 Transmit Channel
USART4 Transmit Channel
USART3 Transmit Channel
USART2 Transmit Channel
USART1 Transmit Channel
USART0 Transmit Channel
SPI1 Transmit Channel
SPI0 Transmit Channel
SSC Transmit Channel
DBGU Receive Channel
USART5 Receive Channel
USART4 Receive Channel
USART3 Receive Channel
USART2 Receive Channel
USART1 Receive Channel
USART0 Receive Channel
ADC Receive Channel
SPI1 Receive Channel
SPI0 Receive Channel
SSC Receive Channel
MCI Transmit/Receive Channel
