contains to default value then clear the bit 15 of PHY register 0 to 0.
The AN983B can assert a signal to wake up the system when it received a Magic Packet from the
network. The Wake on LAN operation is described as follow.
The Wake on LAN enable function is controlled by bit 18 of CSR18; it is loaded from EEPROM
after reset or programmed by driver to enable Wake on LAN function. If the bit 18 of CSR18 is set
and the AN983B receive a Magic Packet, it will assert the PME# signal (drive to low) to indicate
receiving a wake up frame as well as to set the PME status bit (the bit 15 of CSR20).
The AN983B has a built-in capability for Power Management (PM), which controlled by the host
system
The AN983B will provide:
Compatibility with Device Class Power Management Reference
Specification, Rev1.09
Compatibility with ACPI specification, Rev 1.0
Compatibility with PCI Bus Power Management Interface Specification,
Rev 1.1
Compatibility with AMD Magic Packet™ Technology.
Valid destination address that can pass the address filter of the AN983B
The payload of frame must include at least 6 contiguous ‘FF’ followed immediately by
16 repetitions of IEEE address.
The frame can contain multiple ‘six FF + sixteen IEEE address’ pattern.
