Figure 9. Hierarchical Access Methods
Figure 8. shows a normal VAN bus frame. It is initiated with a Start Of Frame (SOF) sequence shown in Figure 10.
The SOF can only be transmitted by an autonomous module. During the preamble the TSS461C will synchronize its
bit rate clock to the data received.

Figure 10. Framing Sequences.
When the complete SOF sequence has been transmitted or received, the circuit will start the transmission or reception
of the identifier field.
All data on the VAN bus, including the identifier and Frame Check Sum (FCS), are transmitted using enhanced
Manchester code.
In enhanced Manchester code three NRZ bits are transmitted first followed by one Manchester bit, then three more
NRZ bits followed by one Manchester bit and so on.
Since the high state is recessive and the low state is dominant, the bus arbitration can be done. If a module wants access
to the bus, it must first listen to the bus during one full End Of Frame (EOF) and one full Inter Frame Spacing (IFS)
period, to determine whether the bus is free or not (i.e. no dominant states received).
