17.4.6.15 Program EEPROM Command
The Program EEPROM operation programs one to four previously erased words in the EEPROM block.
The Program EEPROM operation will confirm that the targeted location(s) were successfully programmed
upon completion.
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.

A Flash word must be in the erased state before being programmed.
Cumulative programming of bits within a Flash word is not allowed.
