MSP430FR50431: LPM3.5

Part Number: MSP430FR50431

We have some questions regarding our use of the MSP430FR50431.  We are trying to wake from LPM3.5 mode using GPIO, but are not getting the expected result.  The user guide which is pointed to by TI’s website does not state it is specifically for this device, so there is some confusion. 


I think it comes down to, how do we restore operation from LPM3.5 using GPIO wake up events on the MSP430FR50431?

There is no “BACKUPMEM” for this device, so I assume we need to store restore info in FRAM correct?

Is there example code for restoring from LPM3.5 on a GPIO wakeup event for this specific device?

Is the user guide we are referencing correct for this device, or is there another one?  (see pic from TI site below)
