De2 board Key0 problem

It seems I can't define Key0, it reset the board every time I press it. Is it some default function?And which nios2 core should I use??

Thanks a lot.

I am writing a uc/os-II program running on nios2 core.

what I am using is in the directory

DE2_demonstrations\SOPC_Builder\Reference_Design\DE2_NIOS

In DE2_NIOS.v I find this line

Reset_Delay delay1 (.iRST(KEY[0]),.iCLK(CLOCK_50),.oRESET(CPU_RESET));

Perhaps that's the reason,I wonder if I can modify that via SOPC Builder.
