Hi

The K70 can write only phrases to Flash (that is, 8 byes on an 8 bye boundary).

If you want to write 8, 16 or 32 bit values you need to write them to a RAM buffer (phrase buffer) of the same size as the phrase to be programmed and always program a complete phrase. You can only program a phrase once and not reprogram a part of it so you can chose to either prepare multiple 8, 16 or 32 bit values in the phrase buffer until full and then write to Flash, or you can chose to write the value that you are interested in to occupy always a complete phrase buffer of its own.
