Section 17 ROM
standby mode. It is not initialized in software standby mode. RAMER settings should be made in
user mode or user program mode.
Flash memory area divisions are shown in table 17.29. To ensure correct operation of the
emulation function, the ROM for which RAM emulation is performed should not be accessed
immediately after this register has been modified. Normal execution of an access immediately
after register modification is not guaranteed.
Bits 7 to 4—Reserved: These bits cannot be modified and are always read as 0.
Bit 3—RAM Select (RAMS): Specifies selection or non-selection of flash memory emulation in
RAM. When RAMS = 1, all flash memory blocks are program/erase-protected.

Bits 2 to 0—Flash Memory Area Selection (RAM2 to RAM0): These bits are used together
with bit 3 to select the flash memory area to be overlapped with RAM (see table 17.29).
