nPME Self Clear

0 = nPME pin is not self clearing.

1 = nPME pin is self clearing.

Note:

When set, the de-assertion delay of the nPME signal is controlled

by the nPME Assert Delay bit of the Miscellaneous Configuration

for additional information.

WoL Configured

This bit may be set by software after the WoL registers are configured. This

sticky bit (and all other WoL related register bits) is reset only via a power

cycle or a pin reset, allowing software to skip programming of the WoL regis-

ters in response to a WoL event.

Note:

Refer to Section 3.8.4, "Wake on LAN (WoL)" for additional infor-

mation.

Perfect DA Frame Received (PFDA_FR)

The MAC sets this bit upon receiving a valid frame with a destination address

that matches the physical address.

R/WC/

NASR

Remote Wakeup Frame Received (WUFR)

The MAC sets this bit upon receiving a valid remote Wakeup Frame.

R/WC/

NASR

Magic Packet Received (MPR)

The MAC sets this bit upon receiving a valid Magic Packet.

R/WC/

NASR

Broadcast Frame Received (BCAST_FR)

NASR

Perfect DA Wakeup Enable (PFDA_EN)

When set, remote wakeup mode is enabled and the MAC is capable of waking

up on receipt of a frame with a destination address that matches the physical

address of the device. The physical address is stored in the MAC Receive

Address A Register (RX_ADDRA), MAC Receive Address B Register

(RX_ADDRB) and MAC Receive Address C Register (RX_ADDRC).

R/W/

NASR

Wakeup Frame Enable (WUEN)

When set, remote wakeup mode is enabled and the MAC is capable of detect-

ing Wakeup Frames as programmed in the Wakeup Filter.
