Upon clearing CCIF to launch the Program EEPROM command, the user-supplied words will be
transferred to the Memory Controller and be programmed if the area is unprotected. The CCOBIX index
value at Program EEPROM command launch determines how many words will be programmed in the
EEPROM block. The CCIF flag is set when the operation has completed.
21.4.7.16 Erase EEPROM Sector Command
The Erase EEPROM Sector operation will erase all addresses in a sector of the EEPROM block.
