The H8/3052BF has 8 kbytes of high-speed static RAM on-chip. 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 H8/3052BF is assigned to addresses H'FDF10 to H'FFF0F in modes 1, 2,
5, and 7, and to addresses H'FFDF10 to H'FFFF0F in modes 3, 4, and 6. The RAM enable bit
