Hello totore69,
The "Device info" for the R5F21258SNFP (ISP-single wire) implementation describes the following signals:
1 - Target VCC check only
2 - MODE
3 - GND (VSS)
4 - Reset
Please double check the situation and let me know if you have any further questions about using this ISP support.
Best regards,

Hello totore69,
Please tell me which signals you have available on your PCB/MCU.
We support the R5F21258SNFP device in two ISP modes:
R5F21258SNFP (ISP)
and
R5F21258SNFP (ISP-single wire)
Please check the software for the full ISP connection details under the "Device info" section.
Depending on which signals you have access to on your PCB/MCU you must chose the appropriate selection in the software.
Best regards,
Neil Parker
