Description
8 RO 0b
Master Data Parity Error Detected (DPD):
Since Parity Error Response is hardwired to disabled (and
the IGD does not do any parity detection), this bit is
hardwired to 0.
Since Parity Error Response is hardwired to disabled (and
the IGD does not do any parity detection), this bit is
hardwired to 0.
7 RO 1b
Fast Back-to-Back (FB2B):
Hardwired to 1. The IGD accepts fast back-to-back when
the transactions are not to the same agent.

66 MHz PCI Capable (66C):
N/A - Hardwired to 0.
N/A - Hardwired to 0.
4 RO 1b
Capability List (CLIST):
This bit is set to 1 to indicate that the register at 34h
provides an offset into the function's PCI Configuration
Space containing a pointer to the location of the first item
in the list.

3 RO 0b
Interrupt Status (INTSTS):
This bit reflects the state of the interrupt in the device.
Only when the Interrupt Disable bit in the command
register is a 0 and this Interrupt Status bit is a 1, will the
devices INTx# signal be asserted.
