You are correct. The other option is to add an 8MHz crystal. BTW external resistor should be about 100Kohm and DCOR bit should be 1.

After combining the document you referred and MSP430x1xx user guide, it seems that DCO clock rate is at most 5MHz with internal resistor only. An external resistor has to be used to achieve 10MHz clock, right? Then the 8Mhz, nominated CPU frequency, cannot be achieve without an external resistor? Thanks! -hd Enrik Berkhan wrote: Haodong Wang wrote: I was wondering that is there an easy way to set up the CPU clock frequency for msp430? We are working on TelosB sensor motes, which feature the MSP430x1xx CPU. We found that the CPU clock is set to 4MHz in TinyOS. Is that difficult to change the clock to 8MHz? http://www-s.ti.com/sc/psheets/slaa074/slaa074.pdf Enrik ------------------------------------------------------------------------- Using Tomcat but need to do more?
