• Channel Buffering
• Channel Control
• Transfer Initiation
• Interrupt
• 4 channels, one 32-bit counter per channel
• Common clock generator, providing Thirteen Different Clocks
• Independent channel programming
– DMA chaining support for multiple non-contiguous data blocks through use of linked
– Scatter support for placing fields into a system memory area from a contiguous
– Gather support for extracting fields from a system memory area into a contiguous
– User enabled auto-reloading of source, destination and control registers from initially
– Auto-loading of source, destination and control registers from system memory at end
– Unaligned system address to data transfer width supported in hardware
– Picture-In-Picture Mode (on DMAC0 only)
– 16-word FIFO (64-word for channel 0 of DMAC0)
– Automatic packing/unpacking of data to fit FIFO width
– Programmable multiple transaction size for each channel
– Support for cleanly disabling a channel without data loss
– Suspend DMA operation
