This register defines the power management capabilities associated with the PCI bus. The register bits are defined below.
Bit [31:27]
: PME Support (R) – Power Management Event Support. This bit field is hardwired to 00
H
; the
SiI3124 does not support PME.
Bit [26]
: PPM D2 Support (R) – PCI Power Management D2 Support. This bit is hardwired to 1.
Bit [25]
: PPM D1 Support (R) – PCI Power Management D1 Support. This bit is hardwired to 1.
Bit [24:22]
: Auxiliary Current (R) – Auxiliary Current. This bit field is hardwired to 000
B
.
Bit [21]
: Dev Special Init (R) – Device Special Initialization. This bit is hardwired to 1 to indicate that the SiI3124
requires special initialization.
Bit [20]
: Reserved (R). This bit is reserved and returns zero on a read.
Bit [19]
: PME Clock (R) – Power Management Event Clock. This bit is hardwired to 0; the SiI3124 does not
support PME.
Bit [18:16]
: PPM Rev (R) – PCI Power Management Revision. This bit field is hardwired to 010
B
to indicate
compliance with the PCI Power Management Interface Specification revision 1.1.
Bit [15:08]
: Next Capability Pointer (R) – PCI Next Capability Pointer. This bit field is hardwired to 40
H
to point
to the 2
Capabilities register, the PCI-X Capability.
Bit [07:00]
: Capability ID (R) – PCI Capability ID. This bit field is hardwired to 01
H
to indicate that this is a PCI
Power Management Capability.
