Unhandled ISR is executed for no apparent reason.

I'm using a MCF52235 along with "Processor Expert" under CW. For some reason, this project executes the unhandled ISR "Cpu_Interrupt" from "CODE\Cpu.c after PE initialization is complete in the main(). In the PE, I've enabled only the GPT0,1 and 2 timer ISRs and when I run it, the common unhandled ISR "Cpu_Interrupt" executes everytime I try single stepping through the code. Any idea why?
