reference clock and rest signal to AX88780. Whenever AX88780 detects magic packet from cable, it will drive
WAKEUP signal to host system. AX88780 defaults in MII mode (after reset before EEPROM auto-loaded) and
uses external PHY. In order to use this function, user must set index 5 of EEPROM to 0x0002 to enable the
internal PHY of AX88780.
The magic packet received by AX88780 is shown as following;
DA + SA + 0x0000 + 0xFFFFFFFFFFFF + (at least repeats 16 times) DA + CRC32
DA = MAC address of AX88780 (6 bytes)
SA = Source address (6 bytes)
AX88780 can support WOL without driver exists. In such situations, system must offer 3.3V voltage,
