New to PIC programming

In the examples for dsPICPro4, why is the clock in project settings set to 80 MHZ when the hardware clock is 10 MHz?

The PLL does multiply the core frequency by nn value. In the case of the dspPIC30F6014A for example, in the Blink example provided with the mikroC Pro for dsPIC, you can see (in red) that the PLLx8 has been used (related registers configured in dsPIC chip), so this multiply the mcu core frequency by 8, and 10MHz (external clock) x PLL_8 = 80MHz.
