19.18.2 RAM Overlap
An example in which flash memory block area EB1 is overlapped is shown below.
Example in which Flash Memory Block Area EB1 is Overlapped
1. Set bits RAMS, RAM2, RAM1, and RAM0 in RAMER to 1, 0, 0, 1, to overlap part of RAM
2. Real-time programming is performed using the overlapping RAM.
3. After the program data has been confirmed, the RAMS bit is cleared, releasing RAM overlap.
4. The data written in the overlapping RAM is written into the flash memory space (EB1).
Notes: 1. When the RAMS bit is set to 1, program/erase protection is enabled for all blocks

onto the area (EB1) for which real-time programming is required.
regardless of the value of RAM2, RAM1, and RAM0 (emulation protection). In this
state, setting the P or E bit in flash memory control register 1 (FLMCR1) will not cause
a transition to program mode or erase mode. When actually programming a flash
memory area, the RAMS bit should be cleared to 0.
