14.3.12Host MAC Wake-up Control and Status Register (HMAC_WUCSR)

Offset:

Ch

Size:

32 bits

This read/write register contains data and control settings pertaining to the Host MAC’s remote wakeup status and capabilities. It is used in conjunction with the Host MAC Wake-up Frame Filter Register (HMAC_WUFF) to fully configure the wake-up frame filter. Refer to Section 9.5, "Wake-up Frame Detection," on page 117 for additional information.

When set, the Host MAC wakes up from power-saving mode on receipt of

 

 

 

a global unicast frame. This is accomplished by enabling global unicasts as

 

 

 

a wakeup frame qualifier. A global unicast frame has the MAC Address [0]
