7.2.2 MII Interrupt Control Register (MICR)
This register implements the MII Interrupt PHY Specific Control register. Sources for interrupt generation include: Energy
Detect State Change, Link State Change,
Speed Status Change, Duplex Status Change, Auto-Negotiation Complete or
any of the counters becoming half-full. The individual interrupt events must be enabled by setting bits in the MII Inter-
rupt Status and Event Control Register (MISR).

TINT
0, RW
Test Interrupt:
Forces the PHY to generate an interrupt to facilitate interrupt test-
ing. Interrupts will continue to be generated as long as this bit re-
mains set.
1 = Generate an interrupt
0 = Do not generate interrupt
1
INTEN
0, RW
Interrupt Enable:
Enable interrupt dependent on the event enables in the MISR reg-
ister.
1 = Enable event based interrupts
0 = Disable event based interrupts
0
INT_OE
0, RW
Interrupt Output Enable:
Enable interrupt events to signal via the PWR_DOWN/INT pin by
configuring the PWR_DOWN/INT pin as an output.
1 = PWR_DOWN/INT is an Interrupt Output
0 = PWR_DOWN/INT is a Power Down Input
