AX88179
USB 3.0 to 10/100/1000M Gigabit Ethernet Controller
Note 1: Remote Wakeup/PME Settings
The offset 05h field of AX88179 EEPROM is used to configure the Remote Wakeup and PME functions.
Please refer to Section 4 “Serial EEPROM/eFuse Memory Map” for the detailed description of EEPROM offset
05h.
The RWU bit of AX88179 EEPROM offset 05h is used to configure the “bmAttributes” field of Standard
Configuration Descriptor that will be reported to the USB host controller when the GET_DESCRIPTOR
command with CONFIGURATION type is issued. Please refer to below table or “Section 9.6.3 Configuration” of
Universal Serial Bus 3.0 Spec for the detailed description of the “bmAttributes” field of Standard Configuration
Descriptor.
The power mode about Bus-powered or Self-powerd is decided by the SELF_PWR pin when chip powers on.
This will updated to the “bmAttributes” field of Standard Configuration Descriptor.
Note 2: Max Power Setting
The low byte of AX88179 EEPROM offset 07h (for bus-powered) field and high byte of AX88179 EEPROM
offset 07h (for self-powered) field are used to configure the “bMaxPower” field of Standard Configuration
Descriptor that will be reported to the USB host controller when the GET_DESCRIPTOR command with
CONFIGURATION type is issued. Please refer to below table or “Section 9.6.3 Configuration” of Universal
Serial Bus 3.0 Spec for the detailed description of the “bMaxPower” field of Standard Configuration Descriptor.
These fields are used to define the Maximum power consumption of the USB device drawn from the USB bus in
this specific configuration when the device is fully operational.
