31-8 Reserved 0 Reserved.
7 LINKSEL 0-1 Link status determination select. Set to 1 to determine link status using the
MLINK pin. Default value is 0 which implies that the link status is determined by
the MDIO state machine.
6 LINKINTENB Link change interrupt enable. Set to 1 to enable link change status interrupts for
PHY address specified in PHYADDRMON. Link change interrupts are disabled
if this bit is cleared to 0.
0 Link change interrupts are disabled
1 Link change status interrupts for PHY address specified in PHYADDRMON bits
are enabled.
