Device Command (CMD) – Offset 4
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 15:11 | 0h | RO | Reserved (Preserved) (RSVD15) SW must preserve the original value when writing. |
| 10 | 0h | RW | Interrupt Disable (ID) Enables the device to assert an INTx#. When set, the Intel HD Audio subsystem's INTx# signal will be de-asserted. When cleared, the INTx# signal may be asserted. Note that this bit does not affect the generation of MSI's. |
| 9 | 0h | RO | Fast Back to Back Enable (FBE) Not implemented. Hardwired to 0. |
| 8 | 0h | RW | SERR Enable (SEN) As a PCI device, this bit is an enable bit for the SERR# driver. |
| 7 | 0h | RO | Wait Cycle Control (WCC) Not implemented. Hardwired to 0. |
| 6 | 0h | RW | Parity Error Response (PER) As a PCI device, this bit controls the device's response to parity errors |
| 5 | 0h | RO | VGA Palette Snoop (VPS) Not implemented. Hardwired to 0. |
| 4 | 0h | RO | Memory Write and Invalidate Enable (MWI) Not implemented. Hardwired to 0. |
| 3 | 0h | RO | Special Cycle Enable (SCE) Not implemented. Hardwired to 0. |
| 2 | 0h | RW | Bus Initiator Enable (BME) 1 = Enable, |
| 1 | 0h | RW | Memory Space Enable (MSE) When set, enables memory space accesses to the Intel HD Audio subsystem. |
| 0 | 0h | RO | I/O Space (IOS) The ACE IP does not implement IO Space, therefore this bit is hardwired to 0. |
