Overview

This LSI is available with 64 kbytes or 128 kbytes of on-chip ROM. The on-chip ROM is

connected to the CPU, direct memory access controller (DMAC) through a 32-bit data bus (figures

19.1 and 19.2). The CPU and DMAC can access the on-chip ROM in 8, 16 and 32-bit widths.

Data in the on-chip ROM can always be accessed in one cycle.
