57.7.8.16.2 Client Node Configuration
In this configuration, the DMA transfers only the data. The identifier must be read by the user in the LIN Identifier register (FLEX_US_LINIR). The LIN mode must be written by the user in FLEX_US_LINMR.
The WRITE buffer contains the data if the USART sends the response (NACT = PUBLISH).
The READ buffer contains the data if the USART receives the response (NACT = SUBSCRIBE).
