Event source:
Specify how the event data (if any) is formed. Normally, the DMA descriptor is used for DMA events, but when the entire
DMA descriptor is built there is no descriptor address to use. The following sources are possible:
00
01
10
DMAQS DMA queue to enqueue DMA descriptor to
RXQUE to deq header DMA descriptor addresses from
Header page size:
Specifies the page size of the buffer that the header is DMAed into. The following encodings are used:
0
1
2
3
4
5
6
7
8
9
RXQUE to deq optional header DMA descriptor addresses from
Enable Split Header Mode (optional header buffer)
Optional header page size:
Specifies the page size of the buffer that the header is DMAed into. The following encodings are used:
0
1

RXQUE to deq page DMA descriptor addresses from
Enable page addresses vs. page descriptor
Page size:
Specifies the page size of the page buffers that the scatter pages are DMAed into. The following encodings are used:
