8.7.2 EEPROM memory organization

The CLRC663 has implemented a EEPROM non-volatile memory with a size of 8 kB.The

EEPROM is organized in pages of 64 bytes. One page of 64 bytes can be programmed at

a time. Defined purposes had been assigned to specific memory areas of the EEPROM,

which are called Sections. Five sections 0..4 with different purpose do exist.

The following figure show the structure of the EEPROM:
