This array of bits are mask control bits for comparison
of each of the MAC Address bytes. When masked, the
MAC does not compare the corresponding byte of
received DA or SA with the contents of MAC
Address3 high and low registers. Each bit controls the
masking of the bytes. You can filter a group of
addresses (known as group address filtering)​ by
masking one or more bytes of the address. The array
index corresponds to the byte (e.g. index 0 is for bits
7:0).
