AX88178
USB to 10/100/1000 Gigabit Ethernet/HomePNA Controller
6.2.2 Remote Wakeup Description
After AX88178 enters into suspend mode, either the USB host or AX88178 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.

PPLS: Primarily PHY Link State.
1: Link is up.
0: Link is down.
SPLS: Secondary PHY Link State.
1: Link is up.
0: Link is down.
FLE: Bulk Out Ethernet Frame Length Error.
1: Proprietary Length field has parity error during Bulk Out transaction.
0: Proprietary Length field has no parity error during Bulk Out transaction.
MDINT: Input level of MDINT pin. The MDINT pin can be connected to MDINT# pin of Ethernet Phy.
1: When MDINT input pin = 1.
0: When MDINT input pin = 0.
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.
