PME Delay Enable
This bit is used to enable the delay of PME output pin 2 assertion.
When this bit is set to 1, the device will not assert the PME output till the device’s all
clocks are running and ready for host access.
When this bit is set to 0, the device will assert the PME output without delay.
This bit is only valid when Auto Wake-Up Enable (bit7) is set to 1 in this register.
Reserved
PME Output Polarity
This bit is used to control the PME output pin 2 polarity.
When this bit is set to 1, the PME output pin 2 is active high.
When this bit is set to 0, the PME output pin 2 is active low.
Wake-on-LAN to PME Output Enable
These four bits are used to enable the PME output pin 2 asserted when one of these
wake-on-LAN events is detected:
Bit 11: is corresponding to receive wake-up frame.
Bit 10: is corresponding to receive magic packet.
Bit 9: is corresponding to link change from down to up.
