R/W Link Signal Change
Indicates that the LNKSTA signal input from the PHY
has changed from high to low or low to high.
To check the current Link state, refer to the LMON bit
in the PHY status register (PSR).

R/W Illegal Carrier Detection
Indicates that the PHY has detected an illegal carrier
on the line. If a change in the signal input from the
PHY occurs before the software recognition period,
the correct information may not be obtained. Refer to
the timing specification for the PHY used.
