In this configuration, the DMAC transfers only the DATA. The Identifier must be read by the user in the LIN Identifier register (US_LINIR). The LIN mode must be written by the user in 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).
