6.5.9 ATA/ ATAPI
The GL824 complies with ATA / ATAPI-6 specification rev 1.0, which supports following data transfer modes:
1.
DMA (Direct Memory Access) data transfer:
DMA data transfer means of data transfer between device and host memory without host processor
intervention.
-
Multiword DMA: Multiword DMA is a data transfer protocol used with the READ DMA, WRITE
DMA, READ DMA QUEUED, WRITE DMA QUEUED and PACKET commands. When a
Multiword DMA transfer is enabled as indicated by IDENTIFY DEVICE or IDENTIFY PACKET
DEVICE data, this data transfer protocol shall be used for the data transfers associated with these
commends. (Please refer to the ATA / ATAPI-6 specification rev 1.0 for more information.)
-
Ultra DMA: Ultra DMA Is a data transfer protocol used with the READ DMA, WRITE DMA,
READ DMA QUEUED, WRITE DMA QUEUED and PACKET commands. When this protocol is
enabled, the Ultra DMA protocol shall be used instead of the Multiword DMA protocol when these
commands are issued by the host. This protocol applies to the Ultra DMA data burst only. (Please
refer to the ATA / ATAPI-6 specification rev 1.0 for more information.)
