16.1
The H8/3008 has 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 can be enabled or disabled with the RAM enable bit (RAME) in the system
control register (SYSCR). When the on-chip RAM is disabled, that area is assigned to external
space in the expanded modes. The on-chip RAM specifications for the H8/3008 are shown in table
16.1.
