Section 18 Ethernet Controller (EtherC)
1. When the receive enable (RE) bit is set, the receiver enters the receive idle state.
2. When an SFD (start frame delimiter) is detected after a receive packet preamble, the receiver
3. In normal mode, if the destination address matches the receiver’s own address, or if broadcast
4. Following data reception from the MII, the receiver carries out a CRC check. The result is
