C Compiler Package for RL78 Family

Switching from Evaluation Editions to Commercial Editions

To upgrade the evaluation edition of a compiler to the commercial edition, enter the license key printed on a purchased compiler package to the e² studio or CS+ IDE (while installing or after having installed the IDE). This lifts the restrictions on functionality of the compiler for the target MCUs, upgrading the compiler to the commercial edition. For details, see the following manuals.
