POWER MANAGEMENT DATA REGISTER – OFFSET E0h
Bit
Function
Type
Description
1:0
Power State
R/W
Indicates the current power state of bridge. If an unimplemented power
state is written to this register, bridge completes the write transaction,
ignores the write data, and does not change the value of the field. Writing
a value of D0 when the previous state was D3 cause a chip reset without
asserting S_RESET#
00: D0 state
01: D1 state (supported if bit[25] offset DCh is HIGH)
10: D2 state (supported if bit[26] offset DCh is HIGH)
11: D3 state
Reset to 0
7:2
Reserved
R/O
Read as 0
8
PME_L Enable
R/O
Read as 0 as bridge does not support the PME# pin.
