DMA Position Upper Base Address — R/W. Upper 32 bits of the DMA Position Buffer Base
Address. This register field must not be written when any DMA engine is running or the DMA
transfer may be corrupted.
Stream Number — R/W. This value reflect the Tag associated with the data being transferred on the
link.
When data controlled by this descriptor is sent out over the link, it will have its stream number
encoded on the SYNC signal.
When an input stream is detected on any of the SDI signals that match this value, the data samples
are loaded into FIFO associated with this descriptor.
Note that while a single SDI input may contain data from more than one stream number, two
different SDI inputs may not be configured with the same stream number.
0000 = Reserved
0001 = Stream 1
........
1110 = Stream 14
1111 = Stream 15
Bidirectional Direction Control — RO. This bit is only meaningful for bidirectional streams; therefore,
this bit is hardwired to 0.
Traffic Priority — RO. Hardwired to 1 indicating that all streams will use VC1 if it is enabled through
the PCI Express* registers.
Stripe Control — RO. This bit is only meaningful for input streams; therefore, this bit is hardwired to
0.
Reserved
Descriptor Error Interrupt Enable — R/W.
0 = Disable
1 = An interrupt is generated when the Descriptor Error Status bit is set.
