Document Table of Contents Address Checking

The MAC function can accept frames with the following address types:
  • 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.
