• Bits 7:4 - LTXDL[3:0]: LIN Transmit Data Length
In LIN mode, this field gives the number of bytes to be transmitted (clamped to 8 Max).
In UART mode this field is unused.
• Bits 3:0 - LRXDL[3:0]: LIN Receive Data Length
In LIN mode, this field gives the number of bytes to be received (clamped to 8 Max).
In UART mode this field is unused.
