RTL8110S-32/RTL8110S-64
Datasheet
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 RTL8110S, e.g. a broadcast, multicast, or unicast
packet addressed to the current RTL8110S 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 RTL8110S is configured to allow direct packet wakeup, e.g. a broadcast, multicast, or
unicast network packet.
*16-bit CRC: The RTL8110S 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).
