From the developer:
The Document Updater is a utility that automatically finds only the documents associated with a specified MCU from a massive document library at the Renesas Web site at a single click, with no occurrences omitted. It also permits you to determine whether the searched document is of the latest version, as well as to download it, so that the documents needed for development can always be maintained up-to-date.
