DP83848I: questions about SNI mode

Part Number: DP83848I

Hello,

 

My customer has some questions about SNI mode as follows.

Q1: DP83848I is powered up as SNI mode (RX_ DV/MII _MODE pin and TXD_ 3/SNI _MODE pin are pulled up). In this case, is it still possible to read/write the registers via MDIO?
Q2: After power up without pulling up RX_ DV/MII _MODE pin and TXD_ 3/SNI _MODE pin, is it possible to enter SNI mode by any register settings?

Best regards,

K.Hirano
