519 / 715 page  Section 15 RAM 15.1 Overview The H8/3003 has 512 bytes of on-chip static 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 suitable for rapid data transfer. The on-chip RAM is assigned to addresses H'FFD10 to H'FFF0F in modes 1 and 2, and addresses H'FFFD10 to H'FFFF0F in modes 3 and 4. The RAM enable bit (RAME) in the system control register (SYSCR) can enable or disable the on-chip RAM. 15.1.1 Block Diagram Figure 15-1 shows a block diagram of the on-chip RAM.
