I am somewhat unfamiliar with using the Reset ISR. I was asked today what would happen if my DSP code on the C6701 got corrupted and the program counter arrived to a invalid instruction or sent to a invalid location. Does the Reset HWI in DSP/Bios get set? I was told that other processors have methods to deal with scenarios like this. Seems like a odd scenario, but we have to worry about a high radiation enviroment so it is a concern. thanks Mike
