The CAN bus has two states during operation: dominant and recessive. A dominant bus state, equivalent to logic low, is when the bus is driven differentially by a driver. A recessive bus state is when the bus is biased to a common mode of VCC / 2 through the high-resistance internal input resistors of the receiver, equivalent to a logic high. The host microprocessor of the CAN node uses the TXD pin to drive the bus and receives data from the bus on the RXD pin. See Figure 25 and Figure 26.
