AX88772_07 ASIX [ASIX Electronics Corporation], AX88772_07 Datasheet - Page 28

• Manufacturer Part Number: AX88772_07
• Description: USB to 10/100 Fast Ethernet/HomePNA Controller
• Manufacturer: ASIX [ASIX Electronics Corporation]

6.2.2 Remote Wakeup Description
After AX88772 enters into suspend mode, either the USB host or AX88772 itself can awake it up and resume back to the
original operation mode before it entered suspend. Following truth table shows the chip setting, wakeup event, and device
response supported by this ASIC. Note that “X” stands for don’t-care.
6.3 Interrupt Endpoint
The Interrupt Endpoint contains 8 bytes of data and its frame format is defined as: A100_BB00_CCDD_EEFF.
Where BB byte in byte 3:
CCDD byte in byte 5 and 6: Primary Phy’s register value, whose offset is given in High byte of EEPROM offset 0Fh.
EEFF byte in byte 7 and 8: Primary Phy’s register value, whose offset is given in Low byte of EEPROM offset 0Fh.
PPLS: Primarily PHY Link State.
SPLS: Secondary PHY Link State.
FLE: Bulk Out Ethernet Frame Length Error.
MDINT: Input level of MDINT pin. The MDINT pin can be connected to MDINT# pin of Ethernet Phy.
