Tool/software:
Hello; I try to make the FR6043 running at 16MHz.
I have downloaded the example "cs_ex2_DCO16MHz". By reading the code, I assume that the 16MHz will output from pin P3.4. But when I probed it, there is nothing coming out from this pin.
Also; I have to comment out the wait insertion line (yellow highlighted line below), otherwise it will show an error message like this.
Thanks!
