Don't write SCKDIV when flashing
...
The target may have already configured its clock to run at a higher frequency and would have set SCKDIV and other dividers at that time. Don't restore the SCKDIV to its default or the flash interface may run too fast and programming will fail.
Otherwise, the default value is fine and there is no need to write SCKDIV.
