MDIO Link change interrupt, masked value. When asserted, a bit indicates that there was an MDIO

 

 

 

link change event (that is, change in the LINK register) corresponding to the PHY address in the

 

 

 

USERPHYSEL register and the corresponding LINKINTENB bit was set. LINKINTMASKED[0] and

 

 

 

LINKINTMASKED[1] correspond to USERPHYSEL0 and USERPHYSEL1, respectively. Writing a 1

 

 

 

will clear the event and writing a 0 has no effect.

 

 

0

No MDIO link change event.

 

 

1

An MDIO link change event (change in the LINK register) corresponding to the PHY address in

 

 

 

MDIO user PHY select register n (USERPHYSELn) and the LINKINTENB bit in USERPHYSELn is

 

 

 

set to 1.
