Table 18.6 Flash Memory Area Divisions - Hitachi H8/3062 Hardware Manual

Bit 3—RAM Select (RAMS): Specifies selection or non-selection of flash memory emulation in
RAM. When RAMS = 1, all flash memory blocks are program/erase-protected.
Bit 3
RAMS Description
0 Emulation not selected
Program/erase-protection of all flash memory blocks is disabled
1 Emulation selected
Program/erase-protection of all flash memory blocks is enabled
Bits 2 to 0—Flash Memory Area Selection (RAM2 to RAM0): These bits are used together
with bit 3 to select the flash memory area to be overlapped with RAM (See table 18.6).

Table 18.6 Flash Memory Area Divisions

RAM Area
H'FFE000 to H'FFEFFF
H'000000 to H'000FFF
H'001000 to H'001FFF
H'002000 to H'002FFF
H'003000 to H'003FFF
H'004000 to H'004FFF
H'005000 to H'005FFF
H'006000 to H'006FFF
H'007000 to H'007FFF
*: Don't care
Note: Flash memory emulation by RAM is not supported in mode 6 (single-chip normal mode);
therefore, although these bits can be written, they should not be set to 1.
When performing flash memory emulation by RAM, the RAME bit in SYSCR must be set to
1.
