AMD SB600 Register Reference Manual Proprietary Page 33
Port–N Interrupt Status - RW - 32 bits [Mem_reg: ABAR + port offset + 10h]
Field Name Bits Default Description
Host Bus Data Error
Status (HBDS)
28 0b Indicates that the HBA encountered a data error
(uncorrectable ECC / parity) when reading from or writing to
system memory.
Host Bus Fatal Error
Status (HBFS)
29 0b Indicates that the HBA encountered a host bus error that it
cannot recover from, such as a bad software pointer. In PCI,
such an indication would be a target or master abort.
Task File Error Status
(TFES)
30 0b This bit is set whenever the status register is updated by the
device and the error bit (bit 0) is set.
Cold Port Detect Status
(CPDS)
31 0b When set, a device status has changed as detected by the
cold presence detect logic. This bit can either be set due to a
non-connected port receiving a device, or a connected port
having its device removed. This bit is only valid if the port
supports cold presence detect as indicated by PxCMD.CPD
set to ‘1’.
Write 1 to clear these status bits.
Port-N Interrupt Enable - RW -32 bits [Mem_reg: ABAR + port offset + 14h]
