10.4.2 Single-Chip Mode (Mode 3)
If the RAME bit is set to 1, accesses to the following addresses are directed to the on-chip RAM.
H8/3257, H8/3256: H'F780 to H'FF7F
H8/325, H8/324: H'FB80 to H'FF7F
H8/323: H'FD80 to H'FF7F
H8/322: H'FE80 to H'FF7F
If the RAME bit is cleared to 0, the on-chip RAM data cannot be accessed. Attempted write access
has no effect. Attempted read access always results in H’FF data being read.
