Hi all,

I'm working with MPC5775K. I‘d like to use the ENET module to control the PHY register. So I configured the EMMFR . I try to read back the data from PHY chip(the inner register is 0x19) and write new data into the register. But it doesn't work. I’m not sure how to use ST PA bit.  The PHY chip is DP83848. Anyone could help me?

Thanks

Regards

Ron
