Section 20 Flash Memory (0.18-µm F-ZTAT Version)
Figure 20.18 shows an example of overlaying flash memory block area EB0.
The flash memory area that can be emulated is the one area selected by bits RAM2 to RAM0 in
RAMER from among the eight blocks, EB0 to EB7, of the user MAT.
To overlay a part of the on-chip RAM with block EB0 for realtime emulation, set the RAMS bit in
RAMER to 1 and bits RAM2 to RAM0 to B'000.
For programming/erasing the user MAT, the procedure programs including a download program
of the on-chip program must be executed. At this time, the download area should be specified so
that the overlaid RAM area is not overwritten by downloading the on-chip program. Since the area
in which the tuned data is stored is overlaid with the download area when FTDAR = H'01, the
tuned data must be saved in an unused area beforehand.
