MSPM0C1103: wake from SHUTDOWN

Part Number: MSPM0C1103

Tool/software:

There is conflicting information about whether or not the MSPM0C1103 and 1104 can actually wake up from shutdown mode with a GPIO level change. This is CRITICAL information and should be consistent across documentation BUT it isn't...

In SLAFS90C (revised Feb 2025) MSPM0C110x, MSPS003 Mixed-Signal Microcontrollers and the datasheet (Feb 2025) it says in shutdown mode "wake is only possible via NRST or SWD." Both documents show  that IOMUX and IO Wakeup are ENABLED in every mode except for shutdown, where they are DISABLED.

The July 2024 TRM says it can wake from a "Wake-up capable IO event, NRST wakeup, SWD debug wakeup." In section 7.2.4 it says "In SHUTDOWN mode, the entire regulated core supply of the device is disabled and the device wakes only from a wake-capable IO that is configured for wakeup, from NRST, or from a debug connection. The IO wake mechanism for exiting SHUTDOWN is managed by IOMUX and is level based. The 5V-tolerant open-drain IOs, high-drive IOs, and certain standard-drive IOs include the additional wakeup logic that can be used to wake the device from a SHUTDOWN operating mode upon a level match."

Then in section 8.10 of the datasheet it says "FastWake" feature enables low-power wakeup from STOP and STANDBY modes for any GPIO port.

So what is the truth???
