winIDEA supports both Single and Double Map Mode programming of Code Flash on Renesas RH850/U2A devices. Single and Double Map Mode are two memory map modes of Code Flash that can be selected by OPBT12. If Double Map Mode is used, Valid Area can be switched with OPBT13.
winIDEA automatically detects the configured mode and adjusts flash operations accordingly.
Option Bytes are part of the Hardware Property Area in Data Flash Memory. Refer to the U2x Hardware Property Area programming and the relevant chapters in RH850/U2A user manuals.
If you program the memory area that doesn't exist in the selected mode, winIDEA will return an error.
