Issue with changing DAC Register via ST-Link

I am having trouble changing any DAC registers using the STLINK debugger. The processor is stopped and the DAC is configured via Cube to be DAC Out 1 with output buffer enabled and no triggering. I let the code run through the Cube generated initialization code and stop at a breakpoint. Any attempt to change a register value or bit is not successful, i.e. the value does not change.

 

Has anyone encountered this?
