17.1
The H8/3007 has 4 kbytes of high-speed static RAM on-chip. The H8/3006 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 H8/3007 is assigned to addresses H'FEF20 to H'FFF1F in modes 1 and 2,
and to addresses H'FFEF20 to H'FFFF1F in modes 3 and 4. The on-chip RAM of the H8/3006 are
assigned to addresses H'FF720 to H'FFF1F in modes 1 and 2, and to addresses H'FFF720 to
H'FFFF1F in modes 3 and 4. The RAM enable bit (RAME) in the system control register
(SYSCR) can enable or disable the on-chip RAM.
