6.1.2 F28P65x_EEPROM.c

Choose which Flash Sectors to use for EEPROM emulation. The sectors chosen (if multiple) should be contiguous and in order from least to greatest. Insert only the First and Last sectors to be used for EEPROM. For example, to use sectors 1-10, insert {1,10}. To only use sector 1, insert {1,1}. A valid configuration will have the following properties.

  • Imply the same amount of sectors for emulation as specified in EEPROM_Config.h
  • Only include a sector(s) that exist on the device
  • Not create an overlap in the Write/Erase Protection Masks between the two units
    • The F28P65x Flash API requires Write/Erase Protection Masks to be configured before programming Flash Memory. Details about the proper configuration of these masks can be found in the F28P65x Flash API Reference Guide.

More details about invalid or dangerous configurations can be found in Section 6.2.1.
