Erasing and programming flash memory takes time, which can make it difficult to tune parameters
and other data in real time. If necessary, real-time updates of flash memory can be emulated by
overlapping the small-block flash-memory area with part of the RAM (H'FC00 to H'FD7F). This
RAM reassignment is performed using bits 7 and 6 of the wait-state control register (WSCR).
After a flash memory area has been overlapped by RAM, the RAM area can be accessed from two
address areas: the overlapped flash memory area, and the original RAM area (H'FC00 to H'FD7F).
Table 19.11 indicates how to reassign RAM.
