Example in which Flash Memory Block Area EB0 is Overlapped
1. Set bits RAMS, RAM2 to RAM0 in RAMCR to 1, 0, 0, 0, to overlap part of RAM onto the
2. Real-time programming is performed using the overlapping RAM.
3. After the program data has been confirmed, clear the RAMS bit to release RAM overlap.
4. Write the data written in the overlapping RAM into the flash memory space (EB0).
Notes: 1. When the RAMS bit is set to 1, program/erase protection is enabled for all blocks

regardless of the value of RAM2 to RAM0 (emulation protection). In this state, setting
the P1 or E1 bit in flash memory control register 1 (FLMCR1), or the P2 or E2 bit in
flash memory control register 2 (FLMCR2), will not cause a transition to program
mode or erase mode. When actually programming or erasing a flash memory area, the
RAMS bit should be cleared to 0.
