I'm running my samd20 with an external xtal at 14.7456MHz without any problem. I want to multiply that frequency. In XMEGA there are multiply factor and divisor factor to do that, but I can't figure out in samd20.
Now I have XOSC->GENERIC CLOCK GENERATOR 0 -> GENERIC CLOCK MULTIPLEXER 0 -> MAIN CLOCK CONTROLLER.
Can I do something like this?
xosc -> generic clock 1 -> generic clock multiplexer 1 then
->DFLL48M -> generic clock 0 -> generic clock multiplexer 0 -> main clock ?
look at the red numbers in this pic:
