Trying to figure out PCLK value on my EMX module


#1

Is there any way of printing out (or calculating) the PCLK value on an EMX module? I’ve searched this forum and the NXP documentation without success. I’ve also seen that someone tried to get this answer without success.

The main reason is that i need to know what is the physical maximum frequency limit the PULSE COUNTER module on the LPC2378 can handle.

Thanks for your help on this

I am not sure about beginner. You are asking a very advanced question :slight_smile:

The clock is CPU clock/4, that is 72/4=18Mhz.
