The Ethernet Media Access Controller (MAC) module implements a 10 Mbps half duplex Ethernet MAC, compatible with the IEEE 802.3 standard and a 10BASE-T1S physical layer transceiver integrated into the LAN8650/1. The communication between the Host and the MAC-PHY is specified in the OPEN Alliance 10BASE-T1x MACPHY Serial Interface (TC6).
