Hi Expert,

For the polarity error on MDI interface, could you please guide me which register can show the polarity? Give a example from other PHY as below.

Thanks!

Hi Ethan!

Bit 9 in MII_REG_13 is the one you're looking for.

Hi Alvaro,

Pol_change_int is 0, means no polarity error;

Pol_change_int is 1, means there’s polarity error, right?

And do you know how to clear this bit?

Thanks!

Hi Ethan,

Apologies for the long response time.

By reading the register MII_REG_13, it should clear the set value.

Alvaro
