64 KByte Flash Module (S12XFTMR64K1V1)
CAUTION
A Flash word must be in the erased state before being programmed.
Cumulative programming of bits within a Flash word is not allowed.

Global address [22:16] to
identify the D-Flash block
Global address [15:0] of word to be programmed
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 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
Set if CCOBIX[2:0] < 010 at command launch
Set if CCOBIX[2:0] > 101 at command launch
Set if command not available in current mode (see Table 20-28)
Set if an invalid global address [22:0] is supplied
Set if a misaligned word address is supplied (global address [0] != 0)
Set if the requested group of words breaches the end of the D-Flash block
Set if the selected area of the D-Flash memory is protected
Set if any errors have been encountered during the verify operation
Set if any non-correctable errors have been encountered during the verify
operation
