17.5.5
RAMER specifies the area of flash memory to be overlapped with part of RAM when emulating
real-time flash memory programming. RAMER settings should be made in user mode or user
program mode. 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. For
details, refer to section 17.7, Flash Memory Emulation in RAM.

These bits always read as 0. The write value should
always be 0.
RAM Select
Specifies selection or non-selection of flash memory
emulation in RAM. When RAMS = 1, the flash memory
is overlapped with part of RAM, and all flash memory
block are program/erase-protected.
Flash Memory Area Selection
When the RAMS bit is set to 1, selects one of the
following flash memory areas to overlap the RAM area.
The areas correspond with 1-kbyte erase blocks.
