220.127.116.11. Address Checking
- Unicast address—bit 0 of the destination address is 0.
- Multicast address—bit 0 of the destination address is 1.
- Broadcast address—all 48 bits of the destination address are 1.
The MAC function always accepts broadcast frames. If promiscuous mode is enabled (PROMIS_EN bit in the command_config register = 1), the MAC function omits address filtering and accepts all frames.
