• Manufacturer Part Number: HD6417615
• Description: Hardware Manual
• Manufacturer: Hitachi Semiconductor

Receive Controller: After a frame is received via the MII, the receive controller carries out
address information, frame length, CRC, and other checks, and the receive data is transferred to
memory by the receive E-DMAC. The main functions of the receive controller are as follows:
Command/Status Interface: This interface provides various command/status registers to control
the EtherC, and performs access to PHY-LSI internal registers via the MII.
Checking received frame format
Checking receive frame CRC and frame length
Transfer of own-address, multicast, or broadcast receive frames to memory
Compliant with MII in IEEE802.3u standard
Nibble-byte conversion supporting PHY-LSI speed
Magic Packet monitoring
