NOTE 

Some pins offer multiple GPIO alternate function configuration, while others don’t. For 
example, for LED1 (PB10), it is possible to drive the intensity of the LED through a 
regular GPIO function or through the PWMA function multiplexed on this pin. 
However, for TOUCH_Y7 (PB12), if the GPIO function configuration is different than 
CAT.CSA[15], the touch interface of this board won’t be functional. 

A UART boot loader is pre-loaded on the Atmel AT32UC3L064. To enter this boot 
loader mode, the WAKE pushbutton must be pressed upon reset and then released. 
It is then possible to program the AT32UC3L064 through the UART boot loader. Note 
also that if the Atmel AT32UC3B1256 is running the pre-loaded virtual com port 
firmware, it is possible to program the AT32UC3L064 with the UART boot loader 
through the USB. For detailed information on the AVR UC3 UART boot loader, see 
Section 

A few test points covering the AT32UC3L064 have been placed on the Atmel 
AT32UC3L-EK for the verification of important signals.
