15.3 Operation
When the RAME bit is set to 1, accesses to addresses H'FFD10 to H'FFF0F in modes 1 and 2, and
to addresses H'FFFD10 to H'FFFF0F in modes 3 and 4, are directed to the on-chip RAM. When
the RAME bit is cleared to 0, the off-chip address space is accessed.
Since the on-chip RAM is connected to the CPU by an internal 16-bit data bus, it can be written
and read by word access. It can also be written and read by byte access. Byte data is accessed in
two states using the upper 8 bits of the data bus. Word data starting at an even address is accessed
in two states using all 16 bits of the data bus.
