2.11.2.3 Saving the displayed CPU register contents

By choosing [Save CPU Register Data As...] from the [File] menu, it is possible to open the Save As dialog box and then save the contents of CPU registers in whole to a text file (*.txt) or a CSV file (*.csv).

When saving to a file, CS+ gets latest information from the debug tool.
