PRODUCTION DATA.
This is the normal operating mode of the device. It is selected by setting STB low. The CAN driver and receiver are fully operational and CAN communication is bidirectional. The driver is translating a digital input on TXD to a differential output on CANH and CANL. The receiver is translating the differential signal from CANH and CANL to a digital output on RXD. In recessive state the bus pins are biased to 0.5 × VCC. In dominant state the bus pins (CANH and CANL) are driven differentially apart. Logic high is equivalent to recessive on the bus and logic low is equivalent to a dominant (differential) signal on the bus.
The SPLIT pin is biased to 0.5 × VCC for bus common-mode bus voltage bias stabilization in split termination network applications (see Application and Implementation).
