Hello. i'd like to ask something about system clock in the board MC9S12XEP100.

 

In the Manuel, this board has clock sources to support frequency to system. Things like Oscillator, Phased locked loop.

 

The problem is oscillator in this board only can provide not more than 4MHZ clock though i need a 16Mhz system clock.

 

As i've seen a Manuel, Phased lock loop mode can solve my problem. But i don't understand exactly what that mode is. Is that

 

a mode providing internal system clock source?
