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.
