Appendix B: Register Details
Register (devcfg) DMA_DST_ADDR
Register DMA_DST_ADDR Details
Register (devcfg) DMA_SRC_LEN
Name DMA_DST_ADDR
Software Name DMA_DEST_ADDR
Relative Address 0x0000001C
Absolute Address 0xF800701C
Width 32 bits
Access Type rw
Reset Value 0x00000000
Description DMA Destination address Register: This register contains the destination address for
DMA transfer.
A DMA command consists of source address, destination address, source transfer
length, and destination transfer length.
It is important that the parameters are programmed in the exact sequence as
described.
Field Name Bits Type Reset Value Description
DST_ADDR 31:0 rw 0x0 Destination address for DMA transfer of AXI
write.
Setting SRC_ADDR[1:0] and DST_ADDR[1:0] to
2'b01 will cause the DMA engine to hold the DMA
DONE interrupt until both the AXI and PCAP
interfaces are done with the data transfer.
Otherwise the interrupt will trigger as soon as the
AXI interface is done.

Relative Address 0x00000020
Absolute Address 0xF8007020
Width 32 bits
Access Type rw
Reset Value 0x00000000
Description DMA Source transfer Length Register: This register contains the DMA source
