Hi all,
When Read Protection is set in PFLASHx can I remove the protection by providing the 256-bit password to the Debugger/Programmer Tool?
Thank you in advance !

Hi Christine,
No, enabling Read Protection will lock the debug interface. If Read protection is needed and access to pflash could be needed in the future, the user should instrument the code in such a way that the Disable Protection and Resume Protection sequences (PMU sequences) can be executed by an external command (via LIN, UART, CAN, etc.).
Kind regards,
Mr. AURIX™
