Description
Indicates the current power state of the bridge. If an unimplemented power state
is written to this register, the 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
10: D2 state
11: D3 state
Reset to 0
Read as 0
Read as 0 as the bridge does not support the PME# pin.
Read as 0 as the data register is not implemented.
Read as 0 as the data register is not implemented.
Read as 0 as the PME# pin is not implemented.
Description
Primary timeout occurs after 2
Reset to 8000h.
Description
Secondary timeout occurs after 2
Reset to 8000h.
Description
Read as 06h to indicate that these are power management enhanced capability
registers.
Description
Read as 00h. No other ECP registers.
