6.1.11 Power Management Register (xxxxxx50H~PCIPMR)

Bit

Default

Type

Description

31:27

11000

PME_ Support

This field indicates that the power states in which the function may assert PME#. A

value of 0 for any bit indicates that the function is not capable of asserting the PME#

signal while in that power state

bit27

PME# support D0

bit28

PME# support D1

bit29

PME# support D2

bit30

PME# support D3(hot)

bit31

PME# support D3(cold)

DM9106’s bit31~27=11000 indicates PME# can be asserted from D3(hot) &

D3(cold)

These bits can be load from EEPROM word 7 bit [7:3]

26:25

Reserved

These two bits can be load from EEPROM word 7 bit [1:0]

24:22

011

Aux_ Current

This field reports the 3.3Vaux auxiliary current requirement for the PCI function.

The default value of this field is 011 means 160mA and it can be loaded from

EEPROM word 4 bit [15:13] if EEPROM word 4 bit [9] is 1

Reserved

This bit can be load from EEPROM word 7 bit [2]

Reserved

PME# Clock

“0” indicates that no PCI clock is required for the function to generate PME#

18:16

010

Version

A default value of 010 indicates that this function complies with the Revision 1.1 of

the PCI Power Management Interface Specification

This value can be loaded from EEPROM word 4 bit [12:10] if EEPROM word 4 bit

[9] is 1

15:8

00H

Next Item Pointer

The offset into the function’s PCI Configuration Space pointing to the location of

next item in the function’s capability list is “00H”

7:0

01H

Capability Identifier

When “01H” indicates the linked list item as being the PCI Power Management

Registers
