MAC interrupts
Interrupts can be generated from the MAC core as a result of various events.
The ETH_MACSR register describes the events that can cause an interrupt from the MAC
core. You can prevent each event from asserting the interrupt by setting the corresponding
mask bits in the Interrupt Mask register.
The interrupt register bits only indicate the block from which the event is reported. You have
to read the corresponding status registers and other registers to clear the interrupt. For
example, bit 3 of the Interrupt register, set high, indicates that the Magic packet or Wake-on-
LAN frame is received in Power-down mode. You must read the ETH_MACPMTCSR
Register to clear this interrupt event.

MAC filtering
Address filtering
Address filtering checks the destination and source addresses on all received frames and
the address filtering status is reported accordingly. Address checking is based on different
parameters (Frame filter register) chosen by the application. The filtered frame can also be
identified: multicast or broadcast frame.
Address filtering uses the station's physical (MAC) address and the Multicast Hash table for
address checking purposes.
