9.1.23 IDE_CONFIG—IDE I/O Configuration Register (SATA–

D31:F5)

Address Offset: 54h–57h Attribute: R/W

Default Value: 00000000h Size: 32 bits

Note: This register is R/W to maintain software compatibility. These bits have no effect on

hardware.

9.1.24 PID—PCI Power Management Capability Identification

Address Offset: 70h–71h Attribute: RO

Default Value: B001h Size: 16 bits

9.1.25 PC—PCI Power Management Capabilities Register (SATA–

D31:F5)

Address Offset: 72h–73h Attribute: RO

Default Value: 4003h Size: 16 bits

Bit Description

31:24 Reserved

23:16 IDE_CONFIG Field 6 — R/W. This field is R/W to maintain software compatibility. This field has no

effect on hardware.

15 Reserved

14 IDE_CONFIG Field 5 — R/W. This field is R/W to maintain software compatibility. This field has no

effect on hardware.

13 Reserved

12 IDE_CONFIG Field 4 — R/W. This field is R/W to maintain software compatibility. This field has no

effect on hardware.

11:8 Reserved

7:4 IDE_CONFIG Field 3 — R/W. This field is R/W to maintain software compatibility. This field has no

effect on hardware.

3 Reserved

2 IDE_CONFIG Field 2 — R/W. This field is R/W to maintain software compatibility. This field has no

effect on hardware.

1 Reserved

0 IDE_CONFIG Field 1 — R/W. This field is R/W to maintain software compatibility. This field has no

effect on hardware.

Bits Description

15:8 Next Capability (NEXT) — RO. When SCC is 01h, this field will be B0h indicating the next item is

FLR Capability Pointer in the list.

7:0 Capability ID (CID) — RO. Indicates that this pointer is a PCI power management.

Bits Description

15:11 PME Support (PME_SUP) — RO. By default with SCC = 01h, the default value of 00000 indicates

no PME support in IDE mode.

10 D2 Support (D2_SUP) — RO. Hardwired to 0. The D2 state is not supported

9 D1 Support (D1_SUP) — RO. Hardwired to 0. The D1 state is not supported

8:6 Auxiliary Current (AUX_CUR) — RO. PME# from D3COLD state is not supported, therefore this field

is 000b.
