15.1.21 IDE_TIM — IDE Timing Register (SATA–D31:F5)
Address Offset: Primary:
Default Value:
Bit
IDE Decode Enable (IDE) — R/W. Individually enable/disable the Primary or
Secondary decode.
0 = Disable.
1 = Enables the PCH to decode the associated Command Blocks (1F0–1F7h for primary,
15
This bit effects the IDE decode ranges for both legacy and native-Mode decoding.
NOTE: This bit affects SATA operation in both combined and non-combined ATA modes.
14:0 Reserved
15.1.22 PID—PCI Power Management Capability Identification
Register (SATA–D31:F5)
Address Offset: 70h
Default Value:
Bits
Next Capability (NEXT) — RO. When SCC is 01h, this field will be B0h indicating the
15:8
next item is FLR Capability Pointer in the list.
7:0 Capability ID (CID) — RO. Indicates that this pointer is a PCI power management.
15.1.23 PC—PCI Power Management Capabilities Register
(SATA–D31:F5)
Address Offset: 72h
Default Value:
f
Bits
PME Support (PME_SUP) — RO. By default with SCC = 01h, the default value of
15:11
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
Auxiliary Current (AUX_CUR) — RO. PME# from D3
8:6
therefore this field is 000b.
Device Specific Initialization (DSI) — RO. Hardwired to 0 to indicate that no device-
5
specific initialization is required.
4 Reserved
PME Clock (PME_CLK) — RO. Hardwired to 0 to indicate that PCI clock is not required to
3
generate PME#.
Version (VER) — RO. Hardwired to 011 to indicates support for Revision 1.2 of the PCI
2:0
Power Management Specification.
