Overview
The H8/3048 and H8/3047 have 4 kbytes of high-speed static RAM on-chip. The H8/3045 and
H8/3044 have 2 kbytes. 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 H8/3048 and H8/3047 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 on-chip
RAM of the H8/3045 and H8/3044 are assigned to addresses H'FF710 to H'FFF0F in modes 1, 2,
5, and 7, and to addresses H'FFF710 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.
