RTL8169S-32/RTL8169S-64
Datasheet
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.
A Wakeup Frame event occurs only when the following conditions are met:
•
The destination address of the received Wakeup Frame is acceptable to the RTL8110S, e.g. a broadcast,
multicast, or unicast address to the current RTL8110S adapter.
•
•
•
The received Wakeup Frame does not contain a CRC error.
The PMEn bit (CONFIG1#0) is set to 1.
The 16-bit CRC* of the received Wakeup Frame matches with the 16-bit CRC* of the sample Wakeup
Frame pattern given by the local machine’s OS. Or, the RTL8169S is configured to allow direct packet
wakeup, e.g. a broadcast, multicast, or unicast network packet.
*16-bit CRC: The RTL8169S supports two normal wakeup frames (covering 64 mask bytes from offset 0
to 63 of any incoming network packet) and three long wakeup frames (covering 128 mask bytes from
offset 0 to 127 of any incoming network packet).
