MSPM0G3519: Documentation issues wrt "Data Bank Protection"

Part Number: MSPM0G3519

TI experts:

The MSPM0 G-Series TRM says the following about "Data Bank Protection":

There are several issues in this regard:

1. The SDK code indicates that the corresponding register is actually called 
   FWPROTMAINDATA (as opposed to FRWPROTDATA).

    
2. The TRM provides no further documentation for this register. The text above is the only mentioning (regardless of naming).
3. The SDK code indicates that there is no 1KB granularity wrt read/write protection. It seems to apply to the entire 4KB (?) range only.

Please provide clarification.

Thx and best regards,
Chris.
