0-3h

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.
