DMA transfer structure.

This structure defines the parameters for a DMA transfer, including source and destination addresses, address increment sizes, transfer size, total transfer length, transfer type, DMA mode, and the peripheral signal that triggers the DMA transfer.

Public Attributes#

uint32_t *
src_addr

Source transfer address.

uint32_t *
dest_addr

Destination transfer address.

uint32_t
src_inc

Source address increment size.

uint32_t
dst_inc

Destination address increment size.

uint32_t
xfer_size

Transfer data size.

uint32_t
transfer_count

Total transfer length.

uint8_t
transfer_type

DMA transfer type.

uint8_t
dma_mode

DMA transfer mode.

uint8_t
signal

Peripheral signal that triggers the DMA transfer (0 for software trigger).
