12description:
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).
