Greetings!

On P145 of UM11126, there is this paragraph

This mechanism is mainly used to recover a part programmed with a corrupted
image. For instance, on boards/products where the ISP pin mechanism in not
affordable and SED pins are accessible or when ISP mode is disabled through the
“Default ISP mode” field in the CMPA_BOOT_CFG configuration word

What is SED pin? The doc or datasheet does not explain it anywhere.

 

Regards.

Hello @steve5528 

 

Thanks for your question.

Sorry, this is a typo. It should be SWD.
