MSPM0-SDK: Inquiry on SysConfig VREF Module Issue: GPIO Configuration Missing in Output Files for Internal Mode, Preventing VREF Control

Part Number: MSPM0-SDK
Other Parts Discussed in Thread: SYSCONFIG, MSPM0G3507

Dear TI Support Team,

I am reporting what appears to be a bug-like behavior in the SysConfig tool for the MSPM0 SDK. I would appreciate your guidance on the phenomenon and any recommended countermeasures.

Phenomenon:
When configuring SysConfig based on the sample code (mspm0_sdk_2_09_00_01\examples\nortos\LP_MSPM0G3507\driverlib\adc12_single_conversion_vref_internal) as attached, the GPIO settings are not included in the output files (ti_msp_dl_config.h), resulting in errors.

My Situation:
In the product I am developing, VREF is used in Internal mode, and to reduce power consumption, I need to switch VREF ON and OFF as needed. Without GPIO definitions, I cannot control this, which is critical for my application.

Could you please explain the cause of this phenomenon and suggest countermeasures? For example, is there a way to manually add GPIO settings or modify SysConfig to ensure they are generated for Internal mode?

Thank you for your assistance. I can provide additional details, such as the attached .syscfg file or error logs, if needed.

Best regards,
Tsuchiya.

    I suppose you are using Pin configuration for VREF pins: 

    The internal pull-up or pull-down resistor is default disabled, so you can left it as unconfigured to avoid these conflict. This doesn't impact your VREF module.
