Hi Jörg,

It wasn't the sales folks whom I asked :-)


Even cracks don't know all these very special things.


Well, suppose there was such a routine (which AFAIK there isn't) and the top notch guys at a company would not know about a tool with so much marketing power. Then it would be time for a huge organizational structuring effort. Because it would mean that there is a company that doesn't know where its assets are. I doubt that's the case with TI.


may be you can deliver teh clock for µC this way external, without the usage from internal fll.

With a fully static design that works. The only thing you have to pay attention to, usually, is the AD converter in there. Some concepts go haywire if you take the clock away in the middle of the game. IIRC some 16bit SD converters then need three "dummy conversions" before you get a good one.


Sure, you have allways to know what you do ;-) Several SD needs more than 3 Cycles to get valid results. SD converters are designed to convert streams not single samples. Therefore they usually don't have a S&H or such things and more often they have included filters...


Which is why, I guess, parts like the MSP430F2013 wouldn't cut it in this application.
