Section 18 ROM
Table 18.3 Flash Memory Erase Blocks
18.5.5
RAMCR specifies the area of flash memory to be overlapped with part of RAM when emulating
real-time flash memory programming. RAMCR initialized to H'F0 by a power-on reset and in
hardware standby mode. It is not initialized by a manual reset and in software standby mode.
RAMCR settings should be made in user mode or user program mode.
Flash memory area divisions are shown in table 18.4. 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.
