The main user interface block of the Atmel AT32UC3L-EK covers all components 
providing a direct interface [visual (output) or tactile (input)] to the user. 

Figure 3-5. AT32UC3L-EK user interface logical view. 

The main user interface offered by the kit is the touch user interface consisting of the 
wheel sensor and the five button sensors. The touch sensors are implemented using 
the QMatrix method (X=6, Y=2). The CAT IP of the Atmel AT32UC3L064 is used, as 
is the ACIFB IP (implied by the use of the QMatrix method). Applications running on 
the AT32UC3L064 need to use the QTouch library for optimal touch events 
management. 

Four general purpose LEDs (labeled LED0, LED1, LED2, LED3) are connected to the 
AT32UC3L064. 

The WAKE pushbutton can be used as a general purpose pushbutton, and is 
connected to the special purpose WAKE_N pin. 

The RST pushbutton is used to generate an external reset to the AT32UC3L064. 

A three-axis accelerometer is connected to three channels of the AT32UC3L064’s 
ADCIFB IP.
