Section 20 Flash Memory
Figure 20.18 shows an example of an overlap on block area EB0 of the flash memory.
Emulation is possible for a single area selected from among the eight areas, from EB0 to EB7, of
user MAT bank 0. The area is selected by the setting of the RAM2 to RAM0 bits in the RAMER.
1. To overlap a part of the RAM on area EB0, to allow real-time programming of the data for this
2. Real-time programming is carried out using the overlapped area of RAM.
In programming or erasing the user MAT, it is necessary to run a program that implements a series
of procedural steps, including the downloading of an on-chip program. In this process, the overlaid
RAM area and the area where the on-chip program is to be downloaded overlap. Therefore, the
data that is to be programmed must be saved beforehand in an area that is not used by the system.
Figure 20.19 shows an example of programming of the data, after emulation has been completed,
to the EB0 area in the user MAT.
