PCI Status (PCISTS_0_4_0_PCI) – Offset 6
PCISTS is a 16-bit status register that reports the occurrence of a PCI compliant Master Abort (MA) and PCI compliant Target Abort (TA).
PCISTS also indicates the DEVSEL# timing that has been set by the DTT Device.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 15 | 0x0 | RO | Detected Parity Error (DPE) The DTT device does not implement this bit and it is hardwired to a 0. |
| 14 | 0x0 | RO | Signaled System Error (SSE) This bit is hardwired to zero. |
| 13 | 0x0 | RO | Received Master Abort Status (RURS) The DTT device does not implement this bit and it is hardwired to a 0. |
| 12 | 0x0 | RO | Received Target Abort Status (RCAS) The DTT device does not implement this bit and it is hardwired to a 0. |
| 11 | 0x0 | RO | Signaled Target Abort Status (STAS) This bit is hardwired to 0. |
| 10:9 | 0x0 | RO | DEVSEL# Timing Status (DEVT) These bits are hardwired to 0. |
| 8 | 0x0 | RO | Master Data Parity Error Detected (DPD) This bit is hardwired to 0. |
| 7 | 0x1 | RO | Fast Back to Back Capable (FB2B) This bit is hardwired to 1. |
| 6 | 0h | RO | Reserved |
| 5 | 0x0 | RO | Primary 66 MHz Capable (PCI66M) The DTT device does not implement this bit and it is hardwired to a 0. |
| 4 | 0x1 | RO | Capabilities List (CLIST) This bit is set to 1 to indicate that the register at 34h provides an offset into the function. PCI |
| 3 | 0x0 | RW/V/L | Interrupt Status (IS) Reflects the state of the INTA# signal at the input of the enable/disable circuit. This bit is set |
| 2:0 | 0h | RO | Reserved |
