1-0 LINKINTMASKED MDIO Link change interrupt, masked value. . When asserted, a bit indicates that there was an

MDIO link change event (i.e. change in the LINK register) corresponding to the PHY address in the

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

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

clear the event and writing 0 has no effect.
