Ok this isnt a question of how but why? and what?
I was finally re-reading the PLL information in the User Manual of the LPC210x
family and i stumbled across this:
"The input frequency is multiplied up the range of 10 MHz to 60 MHz using a
Current Controlled Oscillators (CCO)."
Its on Page 48, "9. Phase Locked Loop (PLL)" second sentence.
Now im lost here because everywhere else in the datasheet and manual it states i
can reach 70Mhz. Which is true?
Can i only get 60Mhz or can i get 70Mhz ?

You caught an error in the manual. This sentence is bogus. The device does run
at 70 MHz.

Yay! So i can in deed make it hit 70Mhz... Now i have to edit my site..
Thanks.
