Node Action
In function of the identifier, the node is concerned, or not, by the LIN response. Consequently,
after sending or receiving the identifier, the USART must be configured. There are three possi-
ble configurations:
This configuration is made by the field, Node Action (NACT), in the US_LINMR register (see
Section
Example: a LIN cluster that contains a Master and two Slaves:
• PUBLISH: the node sends the response.
• SUBSCRIBE: the node receives the response.
• IGNORE: the node is not concerned by the response, it does not send and does not receive
• Data transfer from the Master to the Slave 1 and to the Slave 2:
• Data transfer from the Master to the Slave 1 only:
• Data transfer from the Slave 1 to the Master:
• Data transfer from the Slave1 to the Slave2:
• Data transfer from the Slave2 to the Master and to the Slave1:
the response.
