Hello

It depends what clock speed you are setting up in the chip -> configure menu and also the clock speed defined in the chip -> clock speed menu. You should create a simple LED flashing program eg on for a second and then off for a second. This will let you play around with the configuration settings until you have acheived the correct speed. This should also teach you a lot regarding the configuration settings.
