Flash Memory Emulation in RAM
Making a setting in the RAM emulation register (RAMER) enables part of RAM to be overlapped
onto the flash memory area so that data to be written to flash memory can be emulated in RAM in
real time. After the RAMER setting has been made, accesses cannot be made from the flash
memory area or the RAM area overlapping flash memory. Emulation can be performed in user
mode and user program mode. Figure 21.17 shows an example of emulation of real-time flash
memory programming.
