Note: Since the CS+ which is included with a compiler product might not be the latest version, you may need to upgrade before using it.
Note that simply entering the license key printed on a purchased compiler package upgrades an evaluation edition of "CS+ for CC" to the commercial edition, so you don’t have to re-install CS+ from scratch. For more information, refer to the License information on the CS+ Design Support page.
Online updates are available via the CS+ Update Manager.
We recommend using the latest version.
Updating the RL78 Family device information file for CS+ for CC will add new MCUs to those selectable in the CS+ IDE.
