SpecificationsMIMXRT1050 EVK Board Hardware User’s Guide, User's Guide, Rev. 2, 03/2018NXP Semiconductors 15generates an interrupt (intended to be a software-controllable(power-down). An approximate 5 secondsor more pressing causes a forced OFF. Both boot mode inputs can be disconnected.2.15.3. Reset ButtonThere are two Reset Button on the EVK Board. SW3 is the Power Reset Button. Pressing the SW3 in thePower On state will force to reset the system power except SNVS domain. The Processor will beimmediately turn off and reinitiate a boot cycle from the Processor Power Off state. SW4 is ResetButton.2.15.4. USER ButtonSW8 is the USER Button(GPIO5-00) for developers using. Pressing can produce changes in high andlow levels.2.16. SensorU32 on the EVK Board is a 6-Axis Ecompass (3-Axis Mag, 3-Axis Accel) sensor FXOS8700CQ. TheEcompass is connected to i.MX RT1050 I2C1 port.2.17. User Interface LED IndicatorThere are four LED status indicators located on the EVK Board. The functions of these LEDs include:• Main Power Supply(D3)Green: DC 5V main supply is normal.Red: J2 input voltage is over 5.6V.Off: the board is not powered.• Reset RED LED(D15)• OpenSDA LED(D16)• USER LED(D18)2.18. LCD InterfaceThe enhanced Liquid Crystal Display Interface (eLCDIF) is a general purpose display controller.The eLCDIF block supports the following:• Displays that support moving pictures and require the RGB interface mode (DOTCLK interface).The eLCDIF provides fully programmable functionality to supported interfaces:• Bus master interface to source frame buffer data for display refresh.• 8/16/18/24/32 bit LCD data bus support available depending on I/O mux options.• Programmable timing and parameters for DOTCLK LCD interfaces.
