Flash Memory Emulation in RAM
In the H8/3022F, flash memory programming can be emulated in real time by overlapping the
flash memory with part of RAM (overlap RAM). When the emulation block set in RAMER is
accessed while the emulation function is being executed, data written in the overlap RAM is read.
Emulation should be performed in user mode or user program mode.

Figure 15.3 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.
However, in on-board programming mode, 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.
