描述
The R8C/38A Group is supported only for customers who have already adopted these products. The RL78/G14 Group is recommended for new designs.
The R8C/38A Group of single-chip MCUs incorporate the R8C CPU core, employing sophisticated instructions for a high level of efficiency. With 1Mb of address space, and it is capable of executing instructions at high speed. In addition, the CPU core boasts a multiplier for high-speed operation processing.
Power consumption is low, and the supported operating modes allow additional power control. These MCUs are designed to maximize EMI/EMS performance. Integration of many peripheral functions, including multifunction timer and serial interface, reduces the number of system components. The R8C/38A Group have data flash (1KB × 4 blocks) with the background operation (BGO) function.

- 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PDF 424 KB R01AN1648EJ0101 Rev.1.01 2013年3月31日AI 生成的摘要: CAN communication requires initial settings including clock, bit timing, baud rate, and acceptance filters. Bit timing divides each bit into three segments: Synchronization Segment (SS), Time Segment 1 (TSEG1), and Time Segment 2 (TSEG2). TSEG1 and TSEG2 determine the sampling point and compensate for network delays and phase errors. The timing unit is time quanta (Tq), influenced by clock frequency and baud rate prescaler. Segment settings have specific ranges and restrictions to ensure proper synchronization and communication.
- 应用说明英语PDF 440 KB REJ05B1351-0102 Rev.1.02 2012年6月08日AI 生成的摘要: The document explains the use of UART2 Special Mode 1 for I2C bus communication in the R8C/35C group, focusing on slave transmit and receive operations. It details the initialization of system clocks and UART2 registers, interrupt handling for receive, transmit, and stop condition detection, and the process of acknowledging slave addresses. Data transmission and reception are managed via the U2TB register with specific procedures for each byte. Timing charts illustrate the communication flow between master and slave devices.相关文件：
- 应用说明英语AI 生成的摘要: The document details functional, specification, pin function, and SFR differences among the R8C/38A, R8C/38C, and R8C/38M groups. It compares voltage detection capabilities, oscillator inclusion, interrupt sources, A/D converter performance, flash memory operations, and current consumption. Pin assignments and changes in special function registers (SFRs) are also outlined, highlighting variations in peripheral functions and register bits across the groups.查看更多 (124)
