Section 6   RAM

6.1

Overview

The H8/3150 series has an on-chip static RAM (H8/3152, H8/3155, and H8/3156: 512 bytes;
H8/3153 and H8/3158: 1024 bytes).

The RAM is connected to the CPU by a 16-bit data bus. Both byte data and word data are accessed
in two states, enabling rapid data transfer.

If word access is performed at an odd address in RAM, the word at the preceding even address is
accessed. Normally an even address should be specified for word data.
