20.5.4
EBR2 specifies the flash memory erase area block. EBR2 is initialized to H'00 when the SWE1 bit
in FLMCR1 is 0. Do not set more than one bit at a time, as this will cause all the bits in EBR1 and
EBR2 to be automatically cleared to 0.
Note: * These bits are reserved bits in the H8S/2266 and H8S/2265. Only 0 should be written to
20.5.5
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. Only 0 should be written
to these bits.
When this bit is set to 1, 64 kbytes of EB11 (H'030000 to
H'03FFFF) will be erased.
When this bit is set to 1, 64 kbytes of EB10 (H'020000 to
H'02FFFF) will 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.
