The H8/3029 has 16 kbytes RAM. The RAM is connected to the CPU by a 16-bit data bus. The
CPU accesses both byte data and word data in two states, making the RAM useful for rapid data
transfer.
The on-chip RAM of the H8/3029 is assigned to addresses H'FBF20 to H'FFF1F in modes 1, 2,
and 7, and to addresses H'FFBF20 to H'FFFF1F in modes 3, 4, and 5. The RAM enable bit
(RAME) in the system control register (SYSCR) can enable or disable the on-chip RAM.
