Whether Can I use this physical interface in RMII mode by keeping MII pins remain connected or I need to make NC( not connected ). Please confirm on this</P><P></P><P>Awaiting your reply</P><P></P><P>Regards,</P><P>Shiva kumar L V</P><P>Hardware Design Engineer - EE Excellence center,</P><P>Dover -IIC,</P><P>Web site:www.dovercorporation.com</P><P>Bangalore</P><P>Ph :-8050138478,</P><P>Skype ID :- shivakumarlv25@gmail.com</P><P></P><P></P></BODY></HTML> Thu, 14 May 2015 08:20:40 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/regarding-MII-and-RMII-interface/m-p/432532#M25088 shivakumarlv 2015-05-14T08:20:40Z Re: regarding MII and RMII interface https://community.nxp.com/t5/Kinetis-Microcontrollers/regarding-MII-and-RMII-interface/m-p/432533#M25089 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P></P><P>There is no problem to keep MII pin connected (customer can set MII related pin with another function or keep the default setting at Pin Control Register n (PORTx_PCRn) register [MUX] bits).</P><P>The RMII operates at 50 MHz and requires synchronization between the PHY and the ENET RMII interface clock input(EXTAL).</P><P>Wish it helps.</P><P><BR />Have a great day,<BR />Ma Hui</P><P></P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
