DataFlash 

SO 

If the WLESS J8 connector is configured with 
a jumper on J44.2-4, signal activities over J8.2 
will conflict with the DataFlash SO signal 

12 PA05 

 

If the WLESS J8 connector is configured with 
a jumper on J44.1-3, signal activities over J8.1 
will conflict with the DataFlash SI signal 

To summarize, the Atmel DataFlash cannot be used when using an external module 
on the WLESS connector configured with a jumper on J44.2-4 and/or with a jumper 
on J44.1-3. 

Two test points covering the DataFlash have been placed on the Atmel AT32UC3L-
EK for the verification of important signals.
