Control Block (CPU)
The CPU is a Hitachi SH7706. Based on the SH-3 CPU core using Hitachi's SuperH architecture, the SH7706 is a RISC micro-
processor integrating peripheral functions required for system configuration. High-speed DMA and Bus State Controllers (BSC)
are imbedded for direct connectivity with various memory types. In addition, the serial communications interface, A-D converter,
D-A converter, timer, and real-time clock (RTC) are built in.
In this system, the SH7706 is responsible for the access control of the ROM, SDRAM, peripheral devices, internal RTC, bus
clock generation, and control of other peripheral devices and interfaces using I/O ports.
