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 | 0h | RO | Detected Parity Error (DPE) The DTT device does not implement this bit and it is hardwired to a 0. |
| 14 | 0h | RO | Signaled System Error (SSE) This bit is hardwired to zero. |
| 13 | 0h | RO | Received Master Abort Status (RURS) The DTT device does not implement this bit and it is hardwired to a 0. |
| 12 | 0h | RO | Received Target Abort Status (RCAS) The DTT device does not implement this bit and it is hardwired to a 0. |
| 11 | 0h | RO | Signaled Target Abort Status (STAS) This bit is hardwired to 0. |
| 10:9 | 0h | RO | DEVSEL# Timing Status (DEVT) These bits are hardwired to 0. |
| 8 | 0h | RO | Master Data Parity Error Detected (DPD) This bit is hardwired to 0. |
| 7 | 1h | RO | (FB2BC) Fast Back-to-Back Capable. IOP legacy - set to '1 though no fast b2b will be enabled. |
| 6 | 0h | RO | Reserved |
| 5 | 0h | RO | Primary 66 MHz Capable (PCI66M) The DTT device does not implement this bit and it is hardwired to a 0. |
| 4 | 1h | RO | Capabilities List (CLIST) Capabilities list. DTT supports the extended capabilities linked-list structure. |
| 3 | 0h | RW/V | Interrupt Status (IS) Interrupt Status. Set by HW to '1 when an interrupt is pending and reset by HW to '0 once the interrupt is cleared by SW. |
| 2:0 | 0h | RO | Reserved |
