Tool/software:

Hi,

My customer has a question about the Table 6-2. Pin Attributes in the datasheet.

There are the columns of PIN NAME/IOMUX REG/IOMUX ADDR in the table.

They tried to set the address of PA16 listed in the page 18 by using the CCS, but PA15(DIO15) was set. Also, when the address of PA22 listed in the page 18 was set, PA21 (DIO21) was set.

They’re wondering that the addresses described in the datasheet are wrong. Are they correct ?

Thanks and regards,

Hideaki

Hi Brian,

Thank you for your reply. Since they're using MSPM0L1227SRGER, it's RGE (4x4mm VQFN, 24pin) package.

Thanks and regards,

Hideaki

Hi Hideaki, apologies for the delay! Is this being set up in sysconfig within CCS? I think the pinout in the datasheet is correct, maybe there is something weird going on in CCS that is causing this. If they set a different pin assignment, do you see the same behavior?

Hi Hideaki,

I have brought an empty project into my CCS and assigned the GPIOs to PA16 and PA22. I am showing that the assignments are correctly being set, so I think this may be an issue with how it is being configured on their end.
