5. Flash API ’__api_wr_code_page’ with 0 Data in Length Parameter Field
4131J–CAN–05/06
Version 1.2:
Version 1.4:
Workaround
Use the fuse bit BLJB to start the application in both versions.
When the Flash API ’__api_wr_code_page’ is called with the field ‘nb_data’ equal 0 then 255 data are written in Flash.
Workaround
Include a test on ‘nb_data’ before executing __api_wr_code_page routine.
