Dear Erik,

Oh.. Yes.
Now it is clear to me.

Again. Thank you very much.
Also to Raghu, thank you.

The problem solved quickly.
Thank you for this forum too.

Using a 12 Mhz xtal clocking the chip to 100 Mhz.
Why says that you have to use a 12MHz crystal?

And, there 24 'Mhz' written on the chip, can we clock up to 100 Mhz?
Of course not, you will need another derivative.
1) you can only clock a chip up to its Max frequency.
2) the Cygnal f12x has a max frequency of 100MHz.
3) most high clock frequency derivatives have an internal PLL multiplying the clock.
