MSPM0L1105: PA18引脚为高电平时，代码无法正常运行。

Part Number: MSPM0L1105

如题，我发现我的代码在PA18为低电平时上电能正常运行，在PA18引脚为高电平时，程序完全没有动作。我看手册上面描述PA18有BSL调用功能，会是因为高电平误进入了BSL吗（软件没有使用BSL）？

MSP430FR5043: MSP430FR5043: Accuracy issue of d-tof period deviation caused by cycle slips in abs-tof

martin day — Fri, 09 Oct 2026 06:30:02 GMT

Part Number: MSP430FR5043

Dear TI Support Team,

I have a question regarding the cycle slip issue when using the MSP430FR5043 for ultrasonic water meter design. The LOBE algorithm is being used.

The transducer excitation frequency I am currently using is 1 MHz. Theoretically, a cycle slip should result in a deviation of one complete period, e.g., 1 µs. However, this is not the case in practice. The actual deviation is related to the selected waveform, the type of transducer, and even the flow rate.

I would like to know how this deviation is calculated in TI's algorithm. Please kindly help clarify.

Regards,
Martin Day

MSPM0G3507: Clarification on OPA RRI Register – PMUOPAMP vs CFGBASE in MSPM0G3507

Balaji R G — Tue, 13 Oct 2026 06:49:30 GMT

Part Number: MSPM0G3507

I could not locate the corresponding OPA CFGBASE register description or the relevant PMUOPAMP register field/address information in the G-Series TRM. The MSPM0G3507 datasheet specifies the OPA's RRI characteristics but does not clarify the register address to use for configuring RRI.

Could you please clarify the following?

For the MSPM0G3507 OPA, should RRI be configured through CFGBASE bit 2, as indicated by the HAL/DriverLib, or through the PMUOPAMP register, as stated in Section 21.2.1 of the TRM?
What is the exact register address and bit-field definition for RRI on this device?
If CFGBASE is the correct register, could you point me to the corresponding official register description or clarify why it is missing from the TRM register documentation?

I have attached a screenshot of the relevant TRM section for reference.

Thank you for your help.

您好

感谢您的回复！

目前没有针对性的指导文档。

The data is mismatching in TRM and SDK where the trm says RRI should be written in PMUOPAMP register and SDK is writing in CFGBASE register .
Both SDK and TRM doesnt have the full description of CFGBASE register like the table format.

如题，我想对SWD接口使用密码，我有试过配置NVM的BCR部分，如下图：但是单靠这个无法正常烧录，并且会导致MCU异常，无法烧录。我查找资料又设置烧录的Flash相关设置，然后可以烧录成功，但是烧录进去后无法再次烧录，我有配置密码，如下图：

但是还是无法解锁芯片的SWD。我该怎么办？

Hi,

我正在使用MSPM0L1105做项目，我老板担心其他人反编译出MCU的.Hex文件之类的，所以想对MCU的Flash上锁之类的动作（无法读取Flash中的程序和数据），我想请教一下有什么例程或者资料可以看一下吗？上锁之后如何重烧录的方法可以详细说明一下吗？

CCS是IDE，不会针对IDE出文档和代码。

TI的代码都在SDK里面。

您好，

128-bit password都是ff?

如果您使用正确的密码仍无法解锁，请尝试使用MSPM0_Factory_Reset_Tool 先复位到出厂设置。

根据 Cybersecurity Enablers in MSPM0 MCUs (Rev. B) ，建议芯片工作在“2.6.1.1.2 SWD Security Level 1”模式。

我有看你发的第二个文档，但是里面的第4章中的一个项目和两个脚本在哪里获取？
