Device Status
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 15 | 0h | RW/1C | Detected Parity Error (DPE) Detected Parity Error |
| 14 | 0h | RW/1C | Signaled System Error (SSE) Signaled System Error |
| 13 | 0h | RO | Received Master Abort (RMA) Reserved as 0. |
| 12 | 0h | RO | Received Target Abort (RTA) Reserved as '0'. |
| 11 | 0h | RW/1C | Signaled Target-Abort Status (STA) Reserved as 0. |
| 10:9 | 1h | RO | DEVSEL# Timing Status (DEVT) This 2-bit field defines the timing for DEVSEL# assertion. These read only bits indicate the Intel PCH's DEVSEL# timing when performing a positive decode. Note: Intel PCH generates DEVSEL# with medium time. Note: It is not clear if a PCI master can write to SMBus controller. |
| 8 | 0h | RO | Data Parity Error Detected (DPED) Reserved as 0. |
| 7 | 1h | RO | Fast Back-to-Back Capable (FBC) Reserved as '1'. |
| 6 | 0h | RO | User Definable Features (UDF) Reserved as 0. |
| 5 | 0h | RO | 66 MHz Capable (C_66M) Reserved as 0. |
| 4 | 0h | RO | Capabilities List Indicator (CLI) Hardwired to 0 because there are no capability list structures in this function. |
| 3 | 0h | RO | Interrupt Status (INTS) This bit indicates that an interrupt is pending. It is independent from the state of the Interrupt Enable bit in the command register. |
| 2:0 | 0h | RO | Reserved (RSVD) Reserved |
