BUFFER_DESCRIPTOR_LIST_LOWER_BASE_ADDRESS:
Lower address of the
Buffer Descriptor List. This value should only be modified when the RUN bit is 0 or DMA
transfers may be corrupted. Intel Reserved comment This field becomes WO and 0 s will
be read when the Protect bit is set to 1.

PROTECT:
When this bit is set to 1 bits 31 7 0 of this register are WO and will return 0
s when read. When this bit is cleared to 0 bits 31 7 0 are RW. Note that this bit can only
be changed when all four bytes of this register are written in a single write operation. If
less than four bytes are written this bit retains its previous value. This bit is Intel
Reserved.
