Device ID — RO. This is a 16-bit value assigned to the Intel
Reserved
Interrupt Disable — R/W.
0 = Enable. The function is able to generate its interrupt to the interrupt controller.
1 = Disable. The function is not capable of generating interrupts.
NOTE: The corresponding Interrupt Status bit is not affected by the interrupt enable.
Fast Back to Back Enable (FBE) — RO. Hardwired to 0.
SERR# Enable — RO. Reserved as 0.
Wait Cycle Control (WCC) — RO. Hardwired to 0.
Parity Error Response (PER) — RO. Hardwired to 0.
VGA Palette Snoop (VPS) — RO. Hardwired to 0.
Postable Memory Write Enable (PMWE) — RO. Hardwired to 0.
Special Cycle Enable (SCE) — RO. Hardwired to 0.
Bus Master Enable (BME) — R/W.
0 = Disable
1 = Enable. Intel
Memory Space Enable (MSE) — RO. Hardwired to 0.
I/O Space Enable (IOSE) — R/W. This bit controls access to the I/O space registers.
0 = Disable
1 = Enable accesses to the USB I/O registers. The Base Address register for USB should be
Vendor ID — RO. This is a 16-bit value assigned to Intel
programmed before this bit is set.
