PCI-X to Serial ATA Controller
Data Sheet
This register defines the power management capabilities associated with the PCI bus. The register bits are defined below.

SiI-DS-0160-C
60
Bit [31:24]
: PPM Data (R) – PCI Power Management Data. This bit field is hardwired to 0x19 to indicate a
power consumption of 2.5 Watt.
Bit [23:16]
: Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [15]
:
PME Status (R) – PME Status. This bit is hardwired to 0. The SiI3124 does not support PME.
Bit [14:13]
:
PPM Data Scale (R) – PCI Power Management Data Scale. This bit field is hardwired to 01
B
to
indicate a scaling factor of 100 milliwatts.
Bit [12:09]
:
PPM Data Sel (R/W) – PCI Power Management Data Select. This bit field is set by the system to
indicate which data field is to be reported through the PPM Data bits (although current implementation hardwires
the PPM Data to indicate 2.5 Watt).
Bit [08]
:
PME Ena (R) – PME Enable. This bit is hardwired to 0. The SiI3124 does not support PME.
Bit [07:02]
:
Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [01:00]
:
PPM Power State (R/W) – PCI Power Management Power State. This bit field is set by the system
to dictate the current Power State: 00 = D0 (Normal Operation), 01 = D1, 10 = D2, and 11 = D3 (Hot).
7.2 Internal Register Space – Base Address 0
These registers are 32 or 64 bits wide and are the Global Registers of the SiI3124. Access to this register space is through
the PCI Memory space. In the following table a dashed line separates the register pairs that may be accessed as a 64-bit
register.
