Slave Node Configuration
(DMA)
PDC
The WRITE buffer also contains the Identifier and the DATA, if the USART sends the response
(NACT = PUBLISH).
The READ buffer contains the DATA if the USART receives the response (NACT =
SUBSCRIBE).
In this configuration, the PDC 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 the LIN
Mode register (US_LINMR).
The WRITE buffer contains the DATA if the USART sends the response (NACT=PUBLISH).
