描述
The R8C/29 Group is supported only for customers who have already adopted these products. The RL78/G14 Group is recommended for new designs.
These MCUs are fabricated using a high-performance silicon gate CMOS process, embedding the R8C CPU core, and are packaged in a 20-pin molded-plastic LSSOP. It implements sophisticated instructions for a high level of instruction efficiency. With 1Mb of address space, they are capable of executing instructions at high speed. Furthermore, the R8C/29 Group has on-chip data flash (1KB × 2 blocks). The difference between the R8C/28 Group and R8C/29 Group is only the presence or absence of data flash. Their peripheral functions are the same.

- 应用说明英语AI 生成的摘要: The document explains how to implement single master control communication using the R8C/35C Group EC bus interface to issue a restart condition. It demonstrates sending and receiving data with a digital color sensor (S11059-02DT) by alternating master transmission and reception. The restart condition allows switching data direction without issuing a stop condition, complying with I²C protocol standards such as 7-bit slave addressing, approximately 357 kHz transfer rate, and single master communication.相关文件：

- 应用说明英语AI 生成的摘要: The document explains how to register and uninstall Call Walker within the High-performance Embedded Workshop (HEW). It guides users to launch HEW without opening a workspace, access the Tools Administration menu, and register the Call Walker tool by specifying the registration file path. After registration, Call Walker version 2.3 appears in the menu. Upon uninstalling HEW, users must manually delete the remaining Call Walker directory. It also provides Renesas Electronics website and contact information for support. The revision history notes the first edition release date.

- 应用说明英语AI 生成的摘要: The document specifies the serial communication protocols for the R8C/1x and 2x Series microcontrollers in standard serial I/O modes 2 and 3. It details boot program operations including initial settings, communication with a serial programmer, and control commands for flash memory. Communication formats are asynchronous, with defined data transfer structures. Pin assignments and connection examples for both modes are provided. Initial settings cover selecting communication mode based on the MODE pin level after reset and adjusting the bit rate to 9600 bps through a defined handshake process with the serial programmer.
- 应用说明英语AI 生成的摘要: The R8C/25 Group Timer RA operates in Timer Mode by counting an internally generated source with decrement operation. It reloads the count from a register upon underflow and supports programmable divide ratios. The timer starts and stops via specific bits in the TRACR register, and generates interrupts on underflow. Key registers include TRACR, TRAIOC, TRAMR, TRAPRE, and TRA, which control timer operation, I/O functions, mode selection, prescaler, and count values. Writing to these registers affects timer behavior depending on whether counting is active or stopped.相关文件：
- 应用说明英语AI 生成的摘要: The document explains the Timer RA operation in Pulse Output Mode for the R8C/25 Group. It details how the timer counts an internal source and outputs pulses with inverted polarity on underflow. Key registers such as TRACR, TRAIOC, TRAMR, TRAPRE, and TRA control timer start/stop, output polarity, count source, and prescaler settings. The document also covers interrupt generation, pin functions, and register behaviors during count operations.相关文件：查看更多 (154)
