Error Condition
Set if CCOBIX[2:0] != 010 at command launch
Set if command not available in current mode (see Table 25-27)
Set if an invalid global address [17:0] is supplied
Set if a misaligned word address is supplied (global address [0] != 0)
Set if the requested section breaches the end of the EEPROM block
None
Set if any errors have been encountered during the read or if blank check failed.
Set if any non-correctable errors have been encountered during the read or if
blank check failed.
25.4.6.15 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.
CAUTION
A Flash word must be in the erased state before being programmed.
Cumulative programming of bits within a Flash word is not allowed.

Word 0 program value
Word 1 program value, if desired
Word 2 program value, if desired
Word 3 program value, if desired
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.
