2.4.4.1 Special Considerations when using the DataFlash
The pins PA05, PA06, and PA07 are multiplexed with other components on the AT32UC3L-EK.
The following table highlights the components on the AT32UC3L-EK that might interfere with the DataFlash pins. These components must not be used while using 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 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.
