MSP430FR60471: Soldering profile and debugging with heatgun

Hi,

After soldering, there is impedance reducing at USSXT IN/OUT to GND.

I found soldering profile document and absolute maximum.

Are they also for MSP430FR60471?

Absolute Maximum Ratings for Soldering (Rev. D)

Recommended Soldering Profiles (Rev. J)

When customer use heatgun for debugging, what is proper temperature?

Thanks.
