2.17. User Interface LED Indicator 
There 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 Interface 
The 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. 
If developers want to use LCD, NXP provides an optional LCD module RK043FN02H-CT which has a 
4.3 inches touch-screen and supports a resolution of up to 480*3(RGB)*272. This module contains two 
FPC cables. The LCD interface can be connected to J8(A1-A40) and the CPT interface can be connected 
to J8(B1-B6). LCD modules can be purchased from the NXP website.
