RAMCR selects the RAM area to be used when emulating real-time flash memory programming.
RAMCR initialized to H'F0 by a reset and in hardware standby mode. It is not initialized in
software standby mode. RAMCR settings should be made in user mode or user program mode. *
Note: * When performing flash memory emulation by RAM, the RAME bit in SYSCR must be
RAM area settings are shown in table 18.5. To ensure correct operation of the emulation function,
the ROM for which RAM emulation is performed should not be accessed immediately after this
