TSS461E

They control the VAN Bus rate through a Baud Rate generator according to the formula below:
The TSS461E will transmit and receive data using the pulsed coding mode (i.e optical or radio
link mode). The use of this mode implies communication via the RXD0 input and the non-func-
tionality of the diagnosis system.
Zero: (default at reset) The TSS461E will transmit and receive data using the Enhanced
Manchester code (RXD0, RXD1, RXD2).
Invert TXD output.
Invert RXD inputs.The user can invert the logical levels used on either the TXD output or the
RXD inputs in order to adapt to different line drivers and receivers.
One: A one on either of these bits will invert the respective signals.
Zero: (default at reset). The TSS461E will set TXD to recessive state in Idle mode and consider
the bus free (recessive states on RXD inputs).
