DP83TG720S-Q1: wakeup procedure for DP83TG720S-Q1

Part Number: DP83TG720S-Q1

Hi Expert,

Can you please kindly confirm if the following wakeup flow is correct?

  1. ETH PHY in sleep mode(only V_sleep powered) => remote wakeup => INH activated => VDDA/VDDIO/VDD1P0 switched ON => ETH PHY goes to normal mode => INT output issued if sleep mode change interrupt is enabled.

       2. If for this case, VDD1P0 power is not switched ON, how is the behavior of ETH PHY? Power down mode? 

           ETH PHY in sleep mode(only V_sleep powered) => remote wakeup => INH activated => VDDA/VDDIO switched ON, VDD1P0 still OFF => PHY behavior? Power Down mode? 

Thanks!
