For realtime emulation of the data written to the flash memory using the on-chip RAM, the on-
chip RAM area can be overlaid with several flash memory blocks (user MAT) using the RAM
emulation register (RAMER).
The overlaid area can be accessed from both the user MAT area specified by RAMER and the
overlaid RAM area. The emulation can be performed in user mode and user program mode.
Figure 25.19 shows an example of emulating realtime programming of the user MAT.
