EBR2 specifies the flash memory erase block. EBR2 is initialized to H'00 when a high level is
input to the FWP pin. It is also initialized to H'00, when the SWE bit in FLMCR1 is 0 regardless
of value in the FWP pin. Do not set more than one bit at a time in EBR1 and EBR2, as this will
cause all the bits in EBR1 and EBR2 to be automatically cleared to 0.
19.5.5
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.

Description
Reserved
These bits are always read as 0 and should only be
written with 0
When this bit is set to 1, 64 kbytes of EB11 (H'030000 to
H'03FFFF) are to be erased.
When this bit is set to 1, 64 kbytes of EB10 (H'020000 to
H'02FFFF) are to be erased.
When this bit is set to 1, 64 kbytes of EB9 (H'010000 to
H'01FFFF) will be erased.
When this bit is set to 1, 32 kbytes of EB8 (H'008000 to
H'00FFFF) will be erased.
Description
Reserved
These bits are always read as 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
blocks are program/erase-protected. When RAMS = 0,
the RAM emulation function is disabled.
