1. Overview
1.3 Block Diagram
Figure 1.1 shows a block diagram of the M32C/82 group microcomputer.
The M32C/82 group microcomputer contains ROM and RAM as memory to store instructions and data,
CPU to execute calculations and peripheral functions such as interrupt, timer, serial I/O, DMAC, CRC
calculation circuit, A/D converter, D/A converter, DRAMC, intelligent I/O and ports.
