Hi ti team，

Our client encountered an abnormal situation during the programming of MSPM0L1106TRHBR. The specific problem is shown in the attached picture. Could you please help us identify the cause? Thanks!

Hi Peter，

May I ask what the built-in pull-down resistance of PA2/Rosc is? We have used a voltage divider resistor. Can we set the built-in resistance to be larger?

Hi switch,

According to the datasheet, since it describes as "When the FCL mode is not used, the PA2 pin may be used as a digital input/output pin", so I believe its characteristics are similar to those normal IO, from the IO characteristics, we can see that the pull-down resistance is 40kΩ.

We cannot change the built-in pull-down resistance value through software. You can see the below picture that there is no such pull-down resistance array available for selection, and if you check the IOMUX related registers in MSPM0L1106_TRM, there is no corresponding bit to set either.

Best Regards,
Peter
