Dtransceiver.rst3 CAN Transceiver
13 A CAN transceiver is an external device that converts the logic level signals
14 from the CAN controller to the bus-levels. The bus lines are called
15 CAN High (CAN H) and CAN Low (CAN L).
16 The transmit wire from the controller to the transceiver is called CAN TX,
17 and the receive wire is called CAN RX.
18 These wires use the logic levels whereas the bus-level is interpreted
19 differentially between CAN H and CAN L.
20 The bus can be either in the recessive (logical one) or dominant (logical zero)
21 state. The recessive state is when both lines, CAN H and CAN L, are roughly at
