10 * The emulation represents the EEPROM in flash as a region that is a direct
11 * map of the EEPROM data (EEPROM data) followed by a region where changes to
12 * the EEPROM data (EEPROM changes) are stored. The combination of EEPROM data
13 * and EEPROM changes form a EEPROM page (see drawing below). Changes to EEPROM
15 * is determined by the flash write block size and the size of the EEPROM
18 * When there is no more space to store changes a new EEPROM page is taken into
19 * use. This copies the existing data to the EEPROM data area of the new page.
23 * The EEPROM page needs to be a multiple of a flash page size. Multiple EEPROM
27 * The representation of the EEPROM on flash is shown in the next graph.
