PCI Command (PCICMD_0_2_0_PCI) – Offset 4
This 16-bit register provides basic control over the IGD's ability to respond to PCI cycles. The PCICMD Register in the IGD disables the IGD PCI compliant master accesses to main memory.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 15:11 | 0x0 | RSV | RESERVED (Reserved_0) The field 'Reserved' in register 'PCI Command' does not have a description in the BXML |
| 10 | 0x0 | RW/V | Interrupt Disable (INTDIS) This bit disables the device from asserting INTx#. 0: Enable the assertion of this device's INTx# signal. 1: Disable the assertion of this device's INTx# signal. DO_INTx messages will not be sent to DMI. |
| 9 | 0x0 | RO | Fast Back To Back Enable (FB2B) Not Implemented. Hardwired to 0. |
| 8 | 0x0 | RO | SERR Reporting Enable (SEN) Not Implemented. Hardwired to 0. |
