• Manufacturer Part Number: r4f2426
• Description: 16-bit Single-chip Microcomputer H8s Family / H8s/2400 Series
• Manufacturer: Renesas Electronics Corporation.

This LSI has one channel of synchronous serial communication unit (SSU). 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 19.1 is a block diagram of the SSU.
19.1
• Choice of SSU mode and clock synchronous mode

• Choice of 8/16/24/32-bit width of transmit/receive data
• Full-duplex communication capability
• Consecutive serial communication
• Choice of LSB-first or MSB-first transfer
• Choice of a clock source
• Five interrupt sources
• Module stop mode can be set
Section 19 Synchronous Serial Communication Unit (SSU)
The shift register is incorporated, enabling transmission and reception to be executed
simultaneously.
Seven internal clocks (φ/4, φ/8, φ/16, φ/32, φ/64, φ/128, φ/256) or an external clock
Transmit-end, transmit-data-register-empty, receive-data-full, overrun-error, and conflict error
