• Manufacturer Part Number: RTL8101E-GR
• Description: Intergated Fast Ethernet Controller
• Manufacturer: Realtek Microelectronics

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
Magic Packet Wakeup occurs only when the following conditions are met:
• The destination address of the received Magic Packet is acceptable to the RTL8101E, e.g., a broadcast,
• 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
• The Magic Packet pattern matches, i.e. 6 * FFh + MISC (can be none) + 16 * DID (Destination ID) in
A Wakeup Frame event occurs only when the following conditions are met:
• The destination address of the received Wakeup Frame is acceptable to the RTL8101E, e.g., a
• The received Wakeup Frame does not contain a CRC error.
• The PMEn bit (CONFIG1#0) is set to 1.
• The 16-bit CRC
The corresponding wake-up method (message, beacon, or LANWAKEB) is asserted only when the
following conditions are met:
• The PMEn bit (bit0, CONFIG1) is set to 1.
• The PME_En bit (bit8, PMCSR) in PCI Configuration Space is set to 1.
• The RTL8101E may assert the corresponding wake-up method (message, beacon, or LANWAKEB) in
• A Magic Packet, LinkUp, or Wakeup Frame has been received.
• Writing a 1 to the PME_Status (bit15) of the PMCSR register in the PCI Configuration Space clears

packet wakeup, e.g., a broadcast, multicast, or unicast network packet.
Note: 16-bit CRC: The RTL8101E 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).
