DMA Controller
Peripheral DMA Controller
SAM3U Series
The DMA controller can handle the transfer between peripherals and memory and so receives
the triggers from the peripherals listed below. The hardware interface numbers are also given in
Table 7-4
Table 7-4.

•
•
•
• Acting as one Matrix Master
• Embeds 4 channels:
• Linked List support with Status Write Back operation at End of Transfer
• Word, HalfWord, Byte transfer support.
• Handles high speed transfer of SPI, SSC and HSMCI (peripheral to memory, memory to
• Memory to memory transfer
• Can be triggered by PWM and T/C which enables to generate waveforms though the
peripheral)
External Bus Interface
