"本资源是一份针对瑞萨电子e2 studio开发环境的全面教程，共分六章深入讲解。首先，"简介篇"将引导读者了解e2 studio的基本概念和其在RX系列MCU开发中的重要性。视频随后详细指导如何"下载与安装篇"，确保用户能顺利获取并安装这个强大的集成开发环境。 "创建工程篇"涉及如何使用e2 studio构建新项目，包括配置工具和设置基本项目结构，这对于新手来说是至关重要的入门步骤。接着，"导入篇"教用户如何导入代码库和外设驱动，以便于集成和测试。在"编译调试篇"中，教程会展示如何进行源代码编译，设置编译选项，以及使用内置的调试器进行程序调试，确保代码质量和错误排查。特别值得注意的是，教程还强调了两个关键点：一是避免误操作导致对MTU2和MTU3的受保护寄存器进行读写，这在多功能定时脉冲单元（MTU）的使用中至关重要；二是关于LCD初始化代码的注意事项，同样提到了对MTU2和MTU3的保护。适用的产品版本包括CS+CodeGenerator for RX的V1.08.00及后续版本，e2studio CodeGenerator插件的V3.0.1.9及之后，以及RX1.2版本的AP4编码辅助工具的V1.07.00及以上。教程覆盖的MCU系列包括RX110、RX111、RX113、RX130等RX家族，以及RX230、RX231、RX23T、RX24T和RX24U，还有RX64M和RX71M。这份视频教程旨在为瑞萨电子的e2 studio用户提供一个实用且详尽的开发环境指南，无论是初次接触还是进阶开发者，都能从中获益匪浅。通过跟随教程，用户可以掌握e2 studio的全方位操作，提升编程效率并保证项目质量。"

[Notes]

CS+ Code Generator for RX,

studio Code Generator Plug-in,

AP4 Coding Assistance Tool for RX

Outline

When using the products in the title, note the following points.

1. Prohibition of reading from and writing to registers protected from programming by mistake in multi-function

timer pulse unit 2 (MTU2) and 3 (MTU3)

2. Data output by a pin view

3. LCD initialization code

1. Prohibition of Reading from and Writing to Registers Protected from

Programming by Mistake in Multi-function Timer Pulse Unit 2 (MTU2) and 3

(MTU3)

1.1 Applicable Products

 V1.08.00 and later versions of the CS+ Code Generator for RX

 V3.0.1.9 and later versions of e

studio (V2.0.2 and later versions of the Code Generator plug-in)

 V1.07.00 and later versions of the AP4 coding assistance tool for RX

1.2 Applicable MCUs

 RX family: RX110, RX111, RX113, and RX130 groups

RX230, RX231, RX23T, RX24T, and RX24U groups

RX64M and RX71M groups

1.3 Details

When MTU is used in multi-function timer pulse unit 2 (MTU2) and 3 (MTU3), access to registers/counters

protected from programming by mistake cannot be set to be disabled because the procedure that clears the RWE bit

of the timer read/write enable register (TRWER) or the timer read/write enable register (TRWERA or TRWERB) is

incorrect.

1.4 Workaround

Correct the processing that clears the RWE bit of the timer read/write enable register to "0" in the function

(R_MTU2_Create or R_MTU3_Create) of the multi-function timer pulse unit.

The red text is the modification. This modification is required every time code is generated.
