I cannot recommend tinkering around in the generated files. In the case a build is required the files will get overwritten. In case of Creator updates you are lost.
The delay is surely not taken just as 500ms, it is taken from the specs of the WCO. Would be a bit bad when the WCO doesn't start...
It takes 500ms starting the WCO at high power. You can do that in your program after reset when you like. Start WCO manually. Refer to AN95089.
Hello Bob and thanks for your answer. I understand fully the problems about changes in generated files and that the delay is not just a guess from someone. I have read AN95089 where the WCO is explained.
If I can't change the generated files, it seems to mee, that my only option is to activate ILO as startup source, start WCO manually and disable ILO after 500ms so that WCO is the only clock source. As recommended in AN95089 with external WCO.
Yes, I fully agree to that.
