This register defines the power management capabilities associated with the PCI bus. The register bits are
defined below.
• Bit [31:24]: PPM Data (R) – PCI Power Management Data. This bit field is hardwired to 0x64.
• 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 SiI3114 does not support PME.
• Bit [14:13]: PPM Data Scale (R) – PCI Power Management Data Scale. This bit field is hardwired to 10B to
indicate a scaling factor of 10 mW.
• 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 1 Watt).
• Bit [08]: PME Ena (R) – PME Enable. This bit is hardwired to 0. The SiI3114 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).

This register defines the PCI bus master register for Channel 0/2 in the SiI3114. The register bits are also
mapped to Base Address 4, Offset 00H, Base Address 5, Offset 00H, and Base Address 5, Offset 10H (Note that
these registers are, however, not identical). See “PCI Bus Master – Channel X” section on page 53 for bit
definitions.
