Configuring DP83848C using TSE MAC

https://www.alteraforum.com/forum/attachment.php?attachmentid=8034 Hi,

I tried below code but when i seen in MDC pin in CRO i got the square wave of 2.5MHz as i configure in TSE MAC, but in MDIO pin i seen only DC 3.3V in CRO instead of MDIO Frame. So please suggest if i am wrong in coding. I try to access 0x18 register in PHY DP83848C through MDIO as shown in coding. I try to change the LED Status by forced method.

Is there any setting require in Qsys, Nios-II?
