Thank you all for your replies, this is very helpful information and exactly what i was after... I will digest it all carefully. It does seem on first light that the conclusion is (as per GeekDoc and RobG) that the MSP430 will wake up very quickly when using the internal DCO, and that when using an external Xtal, it has to wait for it to stabilise (order of ms) as it doesn't have a special "magic mode" that accelerates the process. Again thank you all!

One of the great things of these technical forums is that eventually you can get very helpful answers, however unfortunately very often one has to put up with a fair few thoughtless replies in the process, many on the lines of read the f... manual... which obviously is a very enlightened hint... it's a shame when we do not give people the benefit of the doubt and assume they are stupid and/or lazy... and at the same time we don't bother to try to understand the question... On the other hand Kudos to those that have kept the thread positive and useful, much appreciated, this is what makes f

Could you be a bit more forthcoming please? I have read the datasheet and i don't doubt it is there, but i haven't been able to find it, so any indication such as keyword, title of topic that I should be looking for would be much appreciated. Thx

Dear All I am evaluation the MSP430 for a low power application. One of the key points for the application is a quick wake up time from deep sleep mode, where the CPU clock is stopped. I have seen the MSP430 seems to have very fast wake up time from deep sleep, in the order of us, I have not been able to ascertain if this is only when running the DCO as the source of CPU clock, or if it is applicable also when the CPU clock source is an external crystal. Other architectures can also wake up relatively quickly when using the internal RC oscillator as a clock source, but take in the order
