FRAM GPIO ports drive strength registers (PxDS) for real?

Other Parts Discussed in Thread: MSP430FR5739

In the Code Composer Studio debugger for the FRAM MSP430FR5739, I noticed the Registers Window GPIO ports all show a drive strength register (PxDS). Are these registers for real?

I can find no information about them in either the MSP430FR5xx Family User's Guide (slau272) or the MSP430FR573x/MSP430FR572x (slas639) datasheet.

I don't think so. Maybe the register window is mistakenly using the 5x family default list for registers, where all MSPs have them. The FR5xx however, doesn't seem to have them. Neithe rthe users guide nor the dport schematics in the datasheet show any sign of a drive strength setting.

Yes, I can confirm this is a leftover feature for the debugger.

This device does not support programmable drive strength.

Priya, I'd like to start a private conversation with you, unfortunately this is disabled in your profile and I cannot even send a friendship request. (I completely understand why you have disabled this :) )
Could you please start one?
