An example in which flash memory block area EB0 is overlapped is shown in Figure 17.12.
1. The RAM area to be overlapped is fixed at a 1-kbyte area in the range of H'FFD000 to
2. The flash memory area to overlap is selected by RAMER from a 1-kbyte area among one of
3. The overlapped RAM area can be accessed from both the flash memory addresses and RAM
4. When the RAMS bit in RAMER is set to 1, program/erase protection is enabled for all flash
5. A RAM area cannot be erased by execution of software in accordance with the erase algorithm.
6. Block area EB0 contains the vector table. When performing RAM emulation, the vector table
