CCS/LP-CC2652RB: CCS 9.2.0.00013 Register window : UDMA0 Error: unable to read

Please add some context here.

A minimum would be a description of what we as minimum have to do to recreate what you are seeing. 

I got this issue with any my or example project on debug.

Very similar with e2e.ti.com/.../823707

I asked: What do I need to do to get the same issue as you are seeing? Please give a clear step by step description. 

Just debug any project in CCS 9.2.0.00013

To be able to read a register, the module you are trying to read the registers for has to be on. Not all projects uses the DMA and hence it will not be possible to read the registers. 

I assume you actually uses this module and it's on when trying to read?
