DMA Controller
SAM3X/A
SAM3X/A
Table 7-4.
The DMA controller can handle the transfer between peripherals and memory and so receives
the triggers from the peripherals below. The hardware interface numbers are also given in
7-5.
Table 7-5.
Instance Name
• Acting as one Matrix Master
• Embeds 4 (SAM3A and 100-pin SAM3X) or 6 (144-pin SAM3X) channels
• Linked List support with Status Write Back operation at End of Transfer
• Word, HalfWord, Byte transfer support.
• Handles high speed transfer of SPI0-1, USART0-1, SSC and HSMCI (peripheral to memory,
• Memory to memory transfer
• Can be triggered by PWM and T/C which enables to generates waveform though the
32 bytes FIFO for Channel Buffering
8 bytes FIFO for Channel Buffering
memory to peripheral)
