Section 21A ROM (H8S/2636 Group)
Table 21A-7 Flash Memory Erase Blocks (H8S/2636)
21A.7.5 RAM Emulation Register (RAMER)
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 by software standby mode. RAMER settings should be made in
user mode or user program mode.
Flash memory area divisions are shown in table 21A-8. 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.
