MSPM0C1104: Shutdown storage bytes 1 to 3 not writeable

Mario B

Part Number: MSPM0C1104

Tool/software:

Dear colleagues,

I can set Storage byte 0 just fine either by writing with the debugger directly into the corresponding register or by using "DL_SYSCTL_setShutdownStorageByte(DL_SYSCTL_SHUTDOWN_STORAGE_BYTE_0, 0xFF)".

But for the storage bytes 1 to 3 neither method is working.

Do I need to unlock something before writing to these?

Best regards,
Mario

Hi, Mario B

Did you try these code to modify Storage 1 ~ 3?

DL_SYSCTL_setShutdownStorageByte(DL_SYSCTL_SHUTDOWN_STORAGE_BYTE_1, 0x01);
DL_SYSCTL_setShutdownStorageByte(DL_SYSCTL_SHUTDOWN_STORAGE_BYTE_2, 0x02);
DL_SYSCTL_setShutdownStorageByte(DL_SYSCTL_SHUTDOWN_STORAGE_BYTE_3, 0x03);

Regards,

Hi Helic,

unfortunately, this doesn't work out.
I've run following lines:

DL_SYSCTL_setShutdownStorageByte(DL_SYSCTL_SHUTDOWN_STORAGE_BYTE_0, 0xFF);
DL_SYSCTL_setShutdownStorageByte(DL_SYSCTL_SHUTDOWN_STORAGE_BYTE_1, 0x01);
DL_SYSCTL_setShutdownStorageByte(DL_SYSCTL_SHUTDOWN_STORAGE_BYTE_2, 0x02);
DL_SYSCTL_setShutdownStorageByte(DL_SYSCTL_SHUTDOWN_STORAGE_BYTE_3, 0x03);

But the storage bytes 1 - 3 are still 0x00.

Regards,
Mario

Hi, Mario

MSPM0C1104 have only one byte of shutdown storage.

TRM's content is wrong and we will change it in the future.

Sorry for the inconvenience.
