    The PLL in the Extensa 5620 is a ICS9LPR502HGLF, but knowing that won't help you. These chips are TME (Trusted Mode Enable) locked, unless you want to physically modify the hardware... which is possible, and has been done, but isn't for the inexperienced. You need to look up the IC pinout, pull the TME high or low as needed, then modify the overclocking program to understand the proper registers. Hope this helps!
