Overview
The H8/3048B Group has 4 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 H8/3048B Group is assigned to addresses H'FEF10 to H'FFF0F in modes
1, 2, 5, and 7, and to addresses H'FFEF10 to H'FFFF0F in modes 3, 4, and 6. The RAM enable bit
(RAME) in the system control register (SYSCR) can enable or disable the on-chip RAM.
