Table 19.4 Flash Memory Erase Blocks
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 initialized to H'00 by a reset and in hardware
standby mode. It is not initialized in software standby mode. RAMER settings should be made in
user mode or user program mode.
Flash memory area divisions are shown in table 19.5. 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 and 6—Reserved: These bits always read 0.
Bits 5 and 4—Reserved: Only 0 may be written to these bits.
