program. When needed, measures should be taken by user. A periodic interrupt generated by
the WDT can be used as the measures, as an example. In this case, the interrupt generation
period should take into consideration time to program/erase the flash memory.

Immediately after executing the instruction to set the SCO bit to 1, dummy read of the FCCS
must be executed twice.
