You must specify a value at the DataSel input port within the range of 1 to 4 depending on the SPC Mode parameter. If you provide a DataSel value outside this range, the block will, by default, consider the pulse length values for the out-of-range SPC pulse as the value provided at the Pulse length 1 in ticks parameter.
