Capabilities Pointer (CAP_PTR) — RO. This register points to the starting offset of the
USB 2.0 capabilities ranges.
Interrupt Line (INT_LN) — R/W. This data is not used by the Intel
as a scratchpad register to communicate to software the interrupt line that the
interrupt pin is connected to.
Interrupt Pin — RO. This reflects the value of D29IP.EIP (Chipset Config
Registers:Offset 3108:bits 31:28).
NOTE: Bits 7:4 are always 0h
Subsystem ID (SID) — R/W (special). BIOS sets the value in this register to identify
the Subsystem ID. This register, in combination with the Subsystem Vendor ID register,
enables the operating system to distinguish each subsystem from other(s).
NOTE: Writes to this register are enabled when the WRT_RDONLY bit (D29:F7:80h, bit
0) is set to 1.
