19.7
Making a setting in the RAM emulation register (RAMER) enables RAM to be overlapped onto
the part of flash memory area so that data to be programmed to flash memory can be emulated in
the on-chip RAM in real time. Emulation can be performed in user mode or user program mode.
Figure 19.8 shows an example of emulation of real-time flash memory programming.
1. Set RAMER to overlap RAM onto the area for which real-time programming is required.
2. Emulation is performed using the overlapping RAM.
