 /**
  * @brief   Default params
+ *
+ * @note The default parameter set defined here can only be used if a single
+ *       ILI9341 display and only one interface mode is used. If multiple
+ *       ILI9341 displays are used or if multiple interface modes are enabled
+ *       by the modules `lcd_spi`, lcd_parallel and `lcd_parallel_16bit`, a user
+ *       defined parameter set @ref ILI9341_PARAMS has to be defined. In the
+ *       latter case @ref lcd_params_t::spi must then be set to @ref SPI_UNDEF
+ *       for displays with MCU 8080 8-/16-bit parallel interfaces.
