17.1.2
The on-chip RAM is enabled or disabled by the RAME bit in SYSCR. See section 3.2, System
Control Register (SYSCR), for the other SYSCR bits.
Bit 0—RAM Enable (RAME): This bit enables or disables the on-chip RAM. The RAME bit is
initialized to 1 on the rising edge of the RES signal. The RAME bit is not initialized in software
standby mode.

17.2.1
If the RAME bit is set to 1, accesses to addresses H'F780 to H'FF7F in the H8/3437 and H8/3436
and addresses H'FB80 to H'FF7F in the H8/3434 are directed to the on-chip RAM. If the RAME
bit is cleared to 0, accesses to these addresses are directed to the external data bus.
17.2.2
If the RAME bit is set to 1, accesses to addresses H'F780 to H'FF7F in the H8/3437 and H8/3436
and addresses H'FB80 to H'FF7F in the H8/3434 are directed to the on-chip RAM.
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.
