is high (see the EAE bit in Table 1-51 on page 1-116).
descriptor. This field reflects the starting location in system memory of the descriptor
currently loaded into the DB. This value is updated whenever the channel requests a fetch
of a descriptor from the controller.
The value from the fetch FIFO is transferred to the current descriptor pointer register
immediately after the fetch is completed.
This address will be used as the destination for writeback of the modified header dword, if
header writeback notification is enabled.
