ECC Syndrome of CRE or UECC error - Same as EV6.
When CRE or UECC failing transaction: 0000(Bin) = DMA
Read; 0001(Bin) = DMA RMW; 0011(Bin) = S/G Read.
PCI command of transaction when error not CRE or UECC :
0000(Bin) = PCI IACKCycle ; 0001(Bin) = PCI Special Cycle ;
0010(Bin) = PCI I/O Read; 0011(Bin) = PCI I/O Write;
0100(Bin) = Reserved ; 0101(Bin) = PCI PTP Write ;
0110(Bin) = PCI Memory Read ; 0111(Bin) = PCI Memory
Write from CPUx; 1000(Bin) = PCI CSR Read;
If clear = valid <63:56>,<55:52>, and <50:16> error
information if any <11:0> bits are set, otherwise invalid.
If <11> or <10> =set and <51> =clear, <50:19> = System
address <34:3> of erred quadword and <18:16> = 000(Bin);
else if any one of <9:0> =set and <51> = clear, <50:48> =
000(Bin),<47:18> = starting PCI address <31:2> of erred
transaction, <17:16> = 00(Bin) if not DAC; 01(Bin) if DAC SG
Windows 3; 1x(Bin) if Monster Window
MBZ, RAZ
Set = Correctable ECC Error (M or T
2
)
Set = Uncorrectable ECC Error (M or T)
Reserved – MBZ/RAZ
Set = No device select as PCI (M) error
Set = PCI read data parity error as PCI (M)
Set = Target abort error detected as PCI (M)
Set = Address parity error detected as potential PCI
Set = Invalid S/G page table entry detected as PCI
Set = Delayed completion retry time-out error as PCI
Set = PERR# error as PCI (M)
Set = SERR# error as PCI (M or T)
Set = Error occurred / lost after this register locked

M refers to PCI Master; T refers to PCI Target
