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.
