• Manufacturer Part Number: r5f71374an80fpv
• Description: 32-bit Risc Microcomputer Superh?? Risc Engine Family
• Manufacturer: Renesas Electronics Corporation.

This LSI has an independent synchronous serial communication unit (SSU) channel. 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.
15.1

• Choice of 8/16/32-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 standby mode can be set

Section 15 Synchronous Serial Communication Unit (SSU)
The shift register is incorporated, enabling transmission and reception to be executed
simultaneously.
Pφ/4, Pφ/8, Pφ/16, Pφ/32, Pφ/64, Pφ/128, Pφ/256, or an external clock
Transmit end, transmit data register empty, receive data full, overrun error, and conflict error.
The data transfer controller (DTC) can be activated by a transmit data register empty request or
a receive data full request to transfer data.
