描述
The R8C/34M Group is supported only for customers who have already adopted these products. The RL78/G1F Group is recommended for new designs.
The R8C/34M Group of single-chip MCUs incorporates 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/34M Group has data flash (1KB × 4 blocks) with the background operation (BGO) function.

- 应用说明中文AI 生成的摘要: 本文介绍了如何通过I2C总线接口从R8C/36M系列迁移到RL78/G14。详细说明了两者PC总线接口的运行模式及时钟设置差异。RL78/G14支持运行停止、PC总线和唤醒三种模式，R8C/36M支持PC总线和时钟同步模式。还比较了引脚配置和中断处理的差异，并提供了用户手册中时钟及通信设置的参考内容。
- 应用说明英语AI 生成的摘要: The document explains the differences in flash memory functions between the R8C/36M Group and RL78/G14. It outlines the flash memory map and rewrite modes of the R8C/36M Group, including CPU rewrite mode, standard serial I/O mode, and parallel MO mode. The user ROM area is divided into blocks and can be rewritten using different methods, such as software commands from the CPU or external programmers. The boot ROM area stores the standard boot program for serial I/O rewriting.
- 应用说明英语AI 生成的摘要: The document explains how to migrate from the R8C/36M Group's Timer RA to the RL78/G14's Timer RJ, covering five operational modes: timer mode, pulse output mode, event counter mode, pulse width measurement mode, and pulse period measurement mode. Timer RA is an 8-bit timer with an 8-bit prescaler, while Timer RJ is a 16-bit timer with a reload register and down counter. Both timers support equivalent functions, including counting internal or external pulses and measuring pulse width or period. The guide details hardware configurations, software descriptions, option byte settings, function specifications, and flow charts for each mode.相关文件：
- 应用说明英语AI 生成的摘要: The document explains how to migrate the D/A converter functionality from the R8C/36M Group to the RL78/G14 family with 96-KB or larger flash memory. It compares the specifications, highlighting differences such as the reference voltage source (Vref pin for R8C/36M and Vpp pin for RL78/G14) and output pins. It also details register differences and recommends selecting normal mode on RL78/G14 to match R8C/36M operation. Related manuals and technical updates are referenced for further information.
- 应用说明英语AI 生成的摘要: The document explains the migration method from the R8C/36M group to the RL78/G14 family focusing on power control via CPU clock operation modes. It summarizes power control modes in R8C/36M, including standard operating, wait, and stop modes, and compares them with RL78/G14 CPU clock modes such as normal operation, HALT, STOP, and SNOOZE. Key differences include the clock source selection after reset and the inability of RL78/G14 to use the low-speed on-chip oscillator as the CPU clock. Detailed mode transition diagrams and user manual references are provided.
- 应用说明英语AI 生成的摘要: The document details how to migrate timer RD functions from the R8C/36M group to the RL78/G14 family. It compares timer modes, including timer, PWM, reset synchronous PWM, complementary PWM, and PWM3 modes, explaining their functions and differences. RL78/G14 supports similar modes with slight functional enhancements, such as an added PWM function in timer mode. Differences in count sources, forced pulse output cutoff methods, and pin state settings during forced cutoff are also outlined.
- 应用说明英语AI 生成的摘要: The document explains how to migrate synchronous serial communication from the R8C/36M group's SSU to the RL78/G14's SAU. It details the operation modes of both units, showing that the R8C/36M's clock synchronous and 4-wire bus communication modes correspond to the RL78/G14's 3-wire serial I/O (CSI) mode. The chip select line functions differ slightly but are implemented via digital I/O ports or SSIOO pins on the RL78/G14. Sample code focuses on migrating the 4-wire bus mode.相关文件：
