10.5.5 Permanent RxD Recessive Clamping
If the RxD signal is permanently recessive (for example, shorted to V_cc1µC), although there is a message sent on
the bus, the host microcontroller of this transceiver could start a message at any time, because the bus appears
to be idle. To prevent this node from disturbing communication on the bus, the SBC offers permanent RxD
recessive clamping. If the RxD signal is permanently recessive, the failure is diagnosed and the transmitter is
deactivated as long as the error occurs. The transmitter is reactivated only after a SPI command.
