USERPHY1

MDIO Link change interrupt, masked value. When asserted, the bit indicates that there was an
MDIO link change event (that is, change in the LINK register) corresponding to the PHY address in
USERPHYSEL1 and the corresponding LINKINTENB bit was set. Writing a 1 will clear the event,
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 USERPHYSEL1 and the LINKINTENB bit in USERPHYSEL1 is set
to 1.

0

USERPHY0

MDIO Link change interrupt, masked value. When asserted, the bit indicates that there was an
MDIO link change event (that is, change in the LINK register) corresponding to the PHY address in
USERPHYSEL0 and the corresponding LINKINTENB bit was set. Writing a 1 will clear the event,
writing a 0 has no effect.

0

No MDIO link change event.
