12 description:
13 The LAN8650/1 combines a Media Access Controller (MAC) and an Ethernet
14 PHY to enable 10BASE‑T1S networks. The Ethernet Media Access Controller
15 (MAC) module implements a 10 Mbps half duplex Ethernet MAC, compatible
16 with the IEEE 802.3 standard and a 10BASE-T1S physical layer transceiver
17 integrated into the LAN8650/1. The communication between the Host and
18 the MAC-PHY is specified in the OPEN Alliance 10BASE-T1x MACPHY Serial
19 Interface (TC6).
