Overview
The H8/3067 and H8/3066 have 4 kbytes of high-speed static RAM on-chip. The H8/3065 has 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 H8/3067 and H8/3066 is assigned to addresses H'FEF20 to H'FFF1F in
modes 1, 2, and 7, and to addresses H'FFEF20 to H'FFFF1F in modes 3, 4, and 5,and to addresses
H'EF20 to H'FF1F in mode 6. The on-chip RAM of the H8/3065 are assigned to addresses
H'FF720 to H'FFF1F in modes 1, 2, and 7, and to addresses H'FFF720 to H'FFFF1F in modes 3, 4,
and 5, and to addresses H'F720 to H'FF1F in mode 6. The RAM enable bit (RAME) in the system
control register (SYSCR) can enable or disable the on-chip RAM.
