The D3cold_support_PME bit (bit15, PMC register) and the Aux_I_b2:0 bits (bit8:6, PMC register) in PCI configuration space
depend on the existence of Aux power (bit15, PMC) = 1.
If EEPROM D3cold_support_PME bit (bit15, PMC) = 0, the above 4 bits are all 0's.
Example:
If EEPROM D3c_support_PME = 1:
• If Aux. power exists, then PMC in PCI config space is the same as EEPROM PMC
(if EEPROM PMC = C2 F7, then PCI PMC = C2 F7)
• If Aux. power is absent, then PMC in PCI config space is the same as EEPROM PMC except the above 4 bits are all 0’s
(if EEPROM PMC = C2 F7, the PCI PMC = 02 76)
In the above case, if wakeup support is desired when main power is off, it is suggested that the EEPROM PMC be
set to C2 F7 (Realtek EEPROM default value).
If EEPROM D3c_support_PME = 0:
• If Aux. power exists, then PMC in PCI config space is the same as EEPROM PMC
(if EEPROM PMC = C2 77, then PCI PMC = C2 77)
• If Aux. power is absent, then PMC in PCI config space is the same as EEPROM PMC except the above 4 bits are all 0’s.
(if EEPROM PMC = C2 77, then PCI PMC = 02 76)
In the above case, if wakeup support is not desired when main power is off, it is suggested that the EEPROM PMC be
set to 02 76.
Link Wakeup occurs only when the following conditions are met:
• The LinkUp bit (CONFIG3#4) is set to 1, the PMEn bit (CONFIG1#0) is set to 1, and the PME# can be asserted in the
current power state.
• The Link status is re-established.
Magic Packet Wakeup occurs only when the following conditions are met:
• The destination address of the received Magic Packet is acceptable to the RTL8169S, e.g. a broadcast, multicast, or unicast
packet addressed to the current RTL8169S adapter.
• The received Magic Packet does not contain a CRC error.
• The Magic bit (CONFIG3#5) is set to 1, the PMEn bit (CONFIG1#0) is set to 1, and the PME# can be asserted in the current
power state.
• The Magic Packet pattern matches, i.e. 6 * FFh + MISC (can be none) + 16 * DID(Destination ID) in any part of a valid
(Fast) Ethernet packet.
