FBACK_ENB
RO
Fast Back-to-Back Enable: the SSA7785 ThunderBird Avenger, function 2
does not support fast back to back master cycles therefore this bit always
returns a zero.
8
SERR_RESP
RW
System Error Response: When set to 1, the SSA7785 ThunderBird
Avenger, function 2 responds to detected PCI bus address parity errors by
asserting SERR#. When 0, the SSA7785 ThunderBird Avenger ignores
these errors.
7
STEPPING
RO
Address / Data Stepping: Always returns 0.
6
PERR_RESP
RW
Parity Error Response: When set to 1, the SSA7785 ThunderBird Avenger,
function 2 responds to detected PCI bus data parity errors by asserting
PERR#. When 0, the SSA7785 ThunderBird Avenger ignores PCI bus data
parity errors.
