Untested:

Code:

gpio_tgl_gpio_pin(OUTPUT_1);

for (;;) {

    AVR32_GPIO.port[OUTPUT_1 >> 5].ovrt = 1 << (OUTPUT_1 & 0x1F);

}

This did the trick, it shows up on the oscilloscope at ~4.175MHZ. It bounces fairly severely when switching. I will need to work on making the transitions cleaner but i think this will work for what i need it for.

THANKS A TON!
