Status (STS) – Offset 6
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 15 | 0b | RO | Detected Parity Error (DPE) Not implemented. Hardwired to 0. |
| 14 | 0b | RO | SERR# Status (SERRS) Not implemented. Hardwired to 0. |
| 13 | 0b | RW/1C/V | Received Master Abort (RMA) If the completion status received from IOSF is UR, this bit is set. SW writes a 1 to this bit to clear it. |
| 12 | 0b | RW/1C/V | Received Target Abort (RTA) If the completion status received from IOSF is CA, this bit is set. SW writes a 1 to this bit to clear it. |
| 11 | 0b | RO | Signaled Target-Abort (STA) Not implemented. Hardwired to 0. |
| 10:9 | 00b | RO | DEVSEL# Timing Status (DEVT) Does not apply. Hardwired to 0. |
| 8 | 0b | RO | Master Data Parity Error (MDPE) Not implemented. Hardwired to 0. |
| 7 | 0b | RO | Fast Back to Back Capable (FBC) Does not apply. Hardwired to 0. |
| 6 | - | - | Reserved
|
| 5 | 0b | RO | 66 MHz Capable (C66) Does not apply. Hardwired to 0. |
| 4 | 1b | RO | Capabilities List Exists (CLIST) Indicates that the controller contains a capabilities pointer list. The first item is pointed to by looking at configuration offset 34h. |
| 3 | 0b | RO/V | Interrupt Status (IS) Reflects the state of the INTx# signal at the input of the enable/disable circuit. This bit is a 1 when the INTx# is asserted. This bit is a 0 after the interrupt is cleared (independent of the state of the Interrupt Disable bit in the command register). Note that this bit is not set by an MSI. |
| 2:0 | - | - | Reserved
