EEPROMEMU_FLASH_SIZE

#define EEPROMEMU_FLASH_SIZE   ((uintptr_t)(&__eeprom_end - &__eeprom_start))

Total FLASH memory size to use for EEPROM Emulation.

Must be at least 2 sectors large and at least 4x the total amount of EEPROM address space that will be emulated. Larger sizes will result in greater endurance. must be a macro in order to calculate from link time constants.
