In LIN mode, when the multibuffer option is enabled, if a received response (up to eight data bytes) is transferred to the receive buffers (RDy), then a DMA request is generated. If the multibuffer option is disabled, then DMA requests are generated on a byte-per-byte basis until all the expected response data fields are received. This DMA functionality is enabled and disabled using the SET RX DMA and CLR RX DMA bits, respectively.
