Bit Name R/W Function
15 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.
6 UDF RO User Definable Features. Always returns 0.
5 MHz66 RO 66 MHz Capable. Always returns 0.
4:0 R RO Reserved. These bits always return zero.
