Table 3-11. Conflict conditions with the DataFlash.
QFP48 pin GPIO DataFlash signal Conflict conditions
28 PA04 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.
