Flash Memory Emulation in RAM
17.18.1 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 can 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 17.48 shows an example of emulation of real-time flash memory
programming.
