描述
The R8C/34U Group is supported only for the customers who have already adopted these products. For new adoption, please consider other products such as RL78/G1C, RL78/L1C Group.
The R8C/34P Group, R8C/34R 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/34P 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: 本文介绍了如何将R8C/36M群的复位功能迁移到RL78/G14。比较了硬件复位、上电复位、电压监视复位、看门狗定时器复位和软件复位的差异，重点说明了复位后CPU时钟、复位向量、RAM状态、保护状态及外围时钟供应的不同。详细描述了硬件复位和上电复位的迁移步骤，包括时序和电压条件。
- 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 the migration process from the R8C/32C group A/D converter to the RL78/G11 A/D converter, explaining differences in operation modes and result storage. It highlights that RL78/G11 uses a single register for A/D results, unlike R8C/32C which uses multiple registers. It also explains the bit alignment differences in 10-bit and 8-bit resolutions, requiring software adjustments for compatibility. The guide covers various operation modes including one-shot, repeat, single sweep, and repeat sweep modes, with hardware and software descriptions, sample code, and reference materials.相关文件：
- 应用说明英语AI 生成的摘要: The document explains how to migrate timer functions from R8C/36M's Timer RC to RL78/G14's Timer Array Unit (TAU). It covers three main modes: timer mode with input capture, timer mode with output compare, and PWM mode. RL78/G14 uses multiple 16-bit timer channels that can operate independently or combined for high accuracy. The PWM2 mode of R8C/36M is not supported by RL78/G14 but can be implemented using other RL78 series timers.相关文件：

- 应用说明英语AI 生成的摘要: The document details the migration from the R8C/36M group to the RL78/G14 family, focusing on serial interface modes. It compares clock synchronous and asynchronous serial I/O modes in R8C/36M with the Serial Array Unit (SAU) modes in RL78/G14, including 3-wire serial, UART, and simplified I2C communications. Differences in hardware features, interrupt functions, error detection, and clock settings between the two families are highlighted, aiding developers in adapting their serial communication implementations.相关文件：
