Program D-Flash Command
The Program D-Flash operation programs one to four previously erased words in the D-Flash user
partition. 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. The CCOBIX index value at Program D-Flash command
launch determines how many words will be programmed in the D-Flash block. No protection checks are
made in the Program D-Flash operation on the D-Flash block, only access error checks. The CCIF ag is
set when the operation has completed.
