Table 17.4 Flash Memory Erase Blocks
17.3.5
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 17.5. 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.
