Figure 19.8 shows a sample procedure for flash memory block area overlapping.
1. The RAM area to be overlapped is fixed at a 4-kbyte area in the range H'FFFFD000 to
2. The flash memory area to be overlapped is selected by RAMER from a 4-kbyte area of the
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
