R_PERR
RC
Received Parity Error: When set to 1, this bit indicates that the SSA7785
ThunderBird Avenger, function 1 has detected a PCI bus parity error at
least once since this bit was last reset.
14
S_SERR
RC
Signalled System Error: When set to 1, this bit indicates that the SSA7785
ThunderBird Avenger, function 1 has reported a system error on the
SERR# signal at least once since this bit was last reset.
13
SM_ABORT
RO
Signalled Master Abort: The SSA7785 ThunderBird Avenger, function 1,
does not act as a master.
12
RT_ABORT
RO
Received Target Abort: The SSA7785 ThunderBird Avenger, function 1
does not act as a master.
11
ST_ABORT
RC
Signalled Target Abort: When set to 1, this bit indicates that the SSA7785
ThunderBird Avenger, function 1 has signalled a target abort at least once
since this bit was last reset.
10:9
DEVSEL_TM
G
RO
DEVSEL Timing: This field indicates the timing of the DEVSEL output (when
a PCI master is accessing a SSA7785 ThunderBird Avenger, function 1
resource). It always returns 01 (Bin).
00 = Fast
01 = Medium (Default Timing)
10 = Slow
8
S_PERR
RO
Signalled Parity Error: The SSA7785 ThunderBird Avenger, function 1,
does not act as a bus master.
7
F_BK2BK
RO
Always returns 1 to indicate support of fast back to back cycles when the
SSA7785 ThunderBird Avenger, function 1 is the target.
