TPDM CMB subunits support two forms of CMB data set element creation: continuous and trace-on-change collection mode. Continuous change creates CMB data set elements on every CMBCLK edge. Trace-on-change creates CMB data set elements only when a new data set element differs in value from the previous element in a CMB data set. Set CMB_CR.MODE to 0 for continuous CMB collection mode. Set CMB_CR.MODE to 1 for trace-on-change CMB collection mode.
