18.4.6.15 Program D-Flash Command
The Program D-Flash operation programs one to four previously erased words in the D-Flash block. The
Program D-Flash 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.
Upon clearing CCIF to launch the Program D-Flash 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 D-Flash command launch determines how many words will be programmed in the D-Flash block.
The CCIF flag is set when the operation has completed.

Error Condition
FSTAT
ACCERR
Set if CCOBIX[2:0] != 010 at command launch
Set if command not available in current mode (see
)
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 D-Flash block
FPVIOL
None
MGSTAT1
Set if any errors have been encountered during the read or if blank check failed.
MGSTAT0
Set if any non-correctable errors have been encountered during the read or if
blank check failed.
