Slave Node Configuration
Peripheral DMA
Peripheral DMA

In this configuration, the Peripheral DMA Controller transfers only the DATA. The Identifier must
be read by the user in the LIN Identifier register (LINIR). The LIN mode must be written by the
user in the LIN Mode register (LINMR).
The WRITE buffer contains the DATA if the USART sends the response (NACT=PUBLISH).

(NACT=SUBSCRIBE).
IMPORTANT: if the NACT configuration for a frame is PUBLISH, the US_LINMR register, must
be write with NACT=PUBLISH even if this field is already correctly configured, that in order to set
the TXREADY flag and the corresponding Peripheral DMA Controller write transfer request.
