Section 19 ROM
Writing Overlap RAM Data in User Program Mode: When overlap RAM data is confirmed,
the RAMS bit is cleared, RAM overlap is released, and writes should actually be performed to the
flash memory.
When the programming control program is transferred to RAM, ensure that the transfer destination
and the overlap RAM do not overlap, as this will cause data in the overlap RAM to be rewritten.
