Interrupts can be generated from the MAC core as a result of various events.<br />

The ETH_MACSR register describes the events that can cause an interrupt from the MAC<br />

core. You can prevent each event from asserting the interrupt by setting the corresponding<br />

mask bits in the Interrupt Mask register.<br />
