In addition to the VAN specification there is also a pulsed coding of the dominant and recessive states. This mode is
intended to be used with an optical or radio link. In this mode the dominant state for the transmitter is a low pulse, (2x
prescaled clocks at the beginning of the bit) and the recessive state is just a high level.
When receiving in this mode it is not the state of the signal itself which is decoded, but the edges. Also, reception is
imposed on the RxD0 input, and the diagnosis system does not operate correctly.
In addition in this mode there is an internal loopback in the circuit since optical transceivers are not able to receive
the signal that they themselves transmit.

In Figure 7. the pulsed waveforms are shown. In Figure 10. through Figure 16. the low

”
(i.e. blocks of 16
prescaled clocks) should be replaced by the dominant waveform showed in Figure 7. , if the correct representations
for pulsed coding are to be seen.

The VAN bus supports three different module (unit) types:
First, the
Autonomous
module, which is a bus master. It can transmit Start Of Frame (SOF) sequences, it can initiate
data transfers and can receive messages.
Second, the
Synchronous access
module. It cannot transmit SOF sequences, but it can initiate data transfers and
can receive messages.
And finally, the
Slave
module, which can only transmit using an in-frame mechanism and can receive messages.
