SAM3X/A
Notes: 1. TDO pin is set in input mode when the Cortex-M3 Core is not in debug mode. Thus the internal pull-up corresponding to this
PIO line must be enabled to avoid current consumption due to floating input.
2. PIOA: Schmitt Trigger on all, except PA0, PA9, PA26, PA29, PA30, PA31
3. PIOB: Schmitt Trigger on all, except PB14 and PB22
4. PIOC: Schmitt Trigger on all, except PC2 to PC9, PC15 to PC24
5. PIOD: Schmitt Trigger on all, except PD10 to PD30
6. PIOE: Schmitt Trigger on all, except PE0 to PE4, PE15, PE17, PE19, PE21, PE23, PE25, PE29
7. PIOF: Schmitt Trigger on all PIOs
3.1 Design Considerations
In order to facilitate schematic capture when using a SAM3X/A design, Atmel provides a “Sche-
matics Checklist” Application Note. See http://www.atmel.com/products/AT91/
