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.

These bits are always read as 0.
Reserved
Only 0 should be written to this bit.
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.
