28.4.6.16 Erase EEPROM Sector Command

The Erase EEPROM Sector operation will erase all addresses in a sector of the EEPROM block.

Upon clearing CCIF to launch the Erase EEPROM Sector command, the Memory Controller will erase the
selected Flash sector and verify that it is erased. The CCIF flag will set after the Erase EEPROM Sector
operation has completed.
