sithara,
I assume that you want to generate a pulse that lasts for only 1 micro second in the high state. This would not be possible with a digital line, but it is easy to do with a counter. You can have single pulse generation to specify the delay and the length of the pulse. As soon as you use the internal 20 MHz time base the counter should work just fine. The DIO lines on that board are not really meat for high speed switching, but the counter will do. I'm sure you can fine some premade code for this.
