This document by Renesas Electronics Corp. describes the setting method and an application example for rewriting the data flash. It applies to R8C/35C Group.

When rewriting (writing and/or erasing) the flash memory in EW1 mode in the R8C/35C Group, the following show the differences depending on flash memory areas:
- Program ROM area: CPU is in a hold state (states of the I/O ports are retained prior to command execution).
