Data Motion Network Clock

Every platform supports one or more clock sources, one of which is selected by default if you do not make an explicit choice. This default clock is defined by the platform provider, and is used for the data motion network generated by sdsccduring system generation. You can view the platform clocks by selecting the Platformlink in the Generalpanel of the SDx Project Settingswindow. You can select a different platform clock frequency with the Data Motion Network Clock Frequencypull-down menu in the Optionspanel of the SDx Project Settingswindow, or on the command line with the -dmclkidoption.
