21A.4.5 Flash Memory Emulation in RAM
Emulation should be performed in user mode or user program mode. When the emulation block
set in RAMER is accessed while the emulation function is being executed, data written in the
overlap RAM is read.

Figure 21A-4 Reading Overlap RAM Data in User Mode or 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.
