12.3.8.7
DMANDARn contains the address for the next segment descriptor in the chain. In chaining mode, this
register is loaded from the ‘next descriptor’ field of the descriptor to which the current descriptor address
register is pointing.

Byte count. This field contains the number of bytes to transfer. The value in this register is decremented after
each DMA read operation. Maximum transfer size is 64 Mbytes.
Next descriptor address. This field contains the next descriptor address of the next segment descriptor in
memory. It must be aligned on an 8-word boundary.
0 Snooping is disabled on DMA transactions.
1 Snooping is enabled on DMA transactions.
0 No end-of-segment interrupt is generated.
1 An interrupt is generated when the DMA transfer for the next descriptor is finished.
