Note: Bits 7 and 4 in this register are read-only. These bits must not be set to 1. If bits 7 and 4

are set when an EBR1/EBR2 bit is set, EBR1/EBR2 will be initialized to H'00.

RAMCR specifies the area of flash memory to be overlapped with part of RAM when emulating

realtime flash memory programming. RAMCR is initialized to H'00 by a reset and in hardware

standby mode. RAMCR settings should be made in user mode or user program mode.

Flash memory area divisions are shown in table 18.5. 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 1.
