The development board for the ATA6612/ATA6613 provides some placeholders for mounting
additional, optional components. Some already mounted components can be replaced in
order to adapt the LIN node to the users specific requirements. In the following sections these
placeholders and components will be shown and described.
The LIN2.0 specification, as well as the LIN2.1 specification, stipulates that the master node in
a LIN network has to be built up in the way depicted below.
The difference between a master node and a slave node is the additional diode D
together with a serial 1 k resistor between V
