To load correctly the value from the reserved flash location the device must not be in debug mode.<BR /><BR />I apologize for the inconvenience this may cause you. If you have more questions do not hesitate to ask me.<BR />Best regards,<BR />Omar</P> Tue, 03 Aug 2021 19:12:26 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Custm-trim-reference-Ke04-in-debug-mode/m-p/1317533#M46051 Omar_Anguiano 2021-08-03T19:12:26Z
