CC1312R: How to reduce rock bottom current to a lower level.

Hi Ti expert.

I used empty_CC1312R1_LAUNCHXL_tirtos7_ticlang sample code@SDK7.1.

I did not modify any line of source code.

I used the power monitor to measure. Can I reduce the rock bottom current to a lower level?

Now when I use the empty sample code, in the while loop, it is about 212uA. Can this be lower?
