+Note1:\
+ To use RSIP drive, a devvice type should be `R9A07G084M04GBG`. However, choosing `R9A07G084M04GBG` won't allow to select `RSK+RZN2L` board. This example uses LED and external flash memory on `RSK + RZN2L` board. Therefore, the example temporary `R9A07G084M04GBG` for the device type. Updating e2studio or fsp could resolve the issue.
