1.2.5.7 Ethernet MAC Driver Library

The PIC32 Ethernet Controller is a bus host module that interfaces with an off-chip PHY to implement a complete Ethernet node in a system. The following are some of the key features of this module:

• Supports 10/100 Ethernet
• Full-Duplex and Half-Duplex operation
• Broadcast, Multicast and Unicast packets
• Manual and automatic flow control
• Supports Auto-MDIX enabled PHYs
• Reduced Media Independent Interface (RMII) and Media Independent Interface (MII) PHY data interfaces
• Performance statistics metrics in hardware
• RAM descriptor based DMA operation for both receive and transmit path
• Fully configurable interrupts
• Configurable receive packet filtering using:
  • 64-bit Hash Table
  • 64-byte Pattern Match
  • Magic Packet™ Filtering
  • Runt Packet Detection and Filtering
• Supports Packet Payload Checksum calculation
• CRC Check

Support for the Serial Management Interface (SMI) (also known as the MIIM interface) is provided by the Ethernet PHY Driver Library
