• Manufacturer Part Number: h8s-2628
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

This LSI has two independent synchronous serial communication unit (SSU) channels. The SSU
has master mode in which this LSI outputs clocks as a master device for synchronous serial
communication and slave mode in which clocks are input from an external device for synchronous
serial communication. Synchronous serial communication can be performed with devices having
different clock polarity and clock phase. Figure 16.1 is a block diagram of the SSU.
