17.3.1.13 SVID—Subsystem Vendor ID Register (IDER—D22:F2)
Address Offset: 2Ch–2Dh Attribute: R/WO
Default Value: 0000h Size: 16 bits
17.3.1.14 SID—Subsystem ID Register (IDER—D22:F2)
Address Offset: 2Eh–2Fh Attribute: R/WO
Default Value: 8086h Size: 16 bits
17.3.1.15 CAPP—Capabilities List Pointer Register (IDER—D22:F2)
Address Offset: 34h Attribute: RO
Default Value: C8h Size: 8 bits
17.3.1.16 INTR—Interrupt Information Register (IDER—D22:F2)
Address Offset: 3C–3Dh Attribute: R/W, RO
Default Value: 0300h Size: 16 bits
17.3.1.17 PID—PCI Power Management Capability ID Register (IDER—D22:F2)
Address Offset: C8–C9h Attribute: RO
Default Value: D001h Size: 16 bits
Bit Description
15:0 Subsystem Vendor ID (SSVID) — R/WO. Indicates the sub-system vendor identifier. This field
should be programmed by BIOS during boot-up. Once written, this register becomes Read Only. This
field can only be cleared by PLTRST#.
Note: Register must be written as a DWord write with SID register.
Bit Description
15:0 Subsystem ID (SSID) — R/WO. Indicates the sub-system identifier. This field should be
programmed by BIOS during boot-up. Once written, this register becomes Read Only. This field can
only be cleared by PLTRST#.
Note: Register must be written as a DWord write with SVID register.
Bit Description
7:0 Capability Pointer (CP)— R/WO. This field indicates that the first capability pointer is offset C8h
(the power management capability).
Bit Description
15:8 Interrupt Pin (IPIN) — RO. A value of 1h/2h/3h/4h indicates that this function implements
legacy interrupt on INTA/INTB/INTC/INTD, respectively
FunctionValueINTx
(2 IDE)03hINTC
7:0 Interrupt Line (ILINE)— R/W. The value written in this register indicates which input of the
system interrupt controller, the device's interrupt pin is connected to. This value is used by the OS
and the device driver, and has no affect on the hardware.
Bit Description
15:8 Next Capability (NEXT) — RO. Its value of D0h points to the MSI capability.
7:0 Cap ID (CID)— RO. This field indicates that this pointer is a PCI power management.
