Hi Everyone..
I am a Newbie and just starting to write some programm for my lpc2378. At the moment i am trying to make the PLL Setup Sequence for my LPC2378. unfortunately i can't understand this step from User Manual
.. 4) Write to the clock source selection control register to change the clock souce.
I'd have the Main Oscillator as my Clock Source.
CLKSRCSEL = 0x1; /* select main OSC as the PLL clock source */ PLLFEED = 0xaa; PLLFEED = 0x55;
In User Manual can be read that The main oscillator operates at frequencies of 1 MHz to 24 MHz.
My Question: How can i operate the main oscillator with a constant freq? For example 12 MHz ? I need this constant frequenz, so i can configure my PLL
Anyone can help me??
Thank You
