I am wondering if someone can assist me
AT91SAM7x512 datasheet showing that IRQ0 is PA30-->pin80,IRQ1 is PA14-->PA14--->PIN22. However on the Netduino plus schmatic ARM PB26 is IRQ and connect to DM9161's interrupt -->PIN32
It seems to me that there are mistakes on Netduino plus schematics
my question is:
which pins on AT91SAM7x512 are IRQ0 and IRQ1 ?
Many thanks in advance

What do you actually need some help with? I can't find an actual question in your post, but that could be because of my limited knowledge of the AT91SAM7x512 itself

Hi Nissim,
The dedicated-interrupt hardware IRQs (IRQ0, IRQ1, and FIQ) are on MCU pins PA30, PA14 (in peripheral B mode), and PA29 respectively. None of those pins are attached to pin headers on the Netduino.
On the actual AT91SAM7X512-AU MCU (100-pin package), those pins are exposed.
IRQ0 = PA30 = pin 80/100
IRQ1 = PA14 = pin 22/100
FIQ = PA29 = pin 75
For more details, page 9 of the datasheet provides all the pin details.
