What are the power management features of BF60x EMAC?

Question asked by PrasanthR Employee on Mar 27, 2012

BF60x EMAC has no particular power management features built-in, in contrast to legacy parts such as BF537/BF527. This includes magic frames and wake up frames.

 

There is support for wake up using PHYINT signal (a GPIO in BF60x) generated by the external PHY chip. However, since the signal is treated as a GPIO wake up, any device may drive this GPIO, and not just an Ethernet PHY.
