7.2.3 MII Interrupt Status and Misc. Control Register (MISR)
This register contains event status and enables for the interrupt function. If an event has occurred since the last read of this register,
the corresponding status bit will be set. If the corresponding enable bit in the register is set, an interrupt will be generated if the
event occurs. The MICR register controls must also be set to allow interrupts. The status indications in this register will be set even
if the interrupt is not enabled.
