Hi all, Even the same thing I also observed as satheesh. But there is a solution for this. Instead of giving 'RUN' use 'MULTIPLE OPERATION' . In this way code-composer will do single stepping, the number of times 'MULTIPLE OPERATION' you have set. This time is perfect, and I have cross checked it manually. rgds, shashi satheesh wrote: > Hi > The issue of finding execution time is a bit tricky if u r using code > composer studio.
