BDM Functions
Depending on the target part, the BDM controller may feature a hardware breakpoint register. The register holds a value indicating an address in memory. When the target part's CPU accesses that location in memory, the BDM hardware can take control of the target part, stop program execution, and begin operating in Background Mode.

Famous quotes containing the word functions:
“The mind is a finer body, and resumes its functions of feeding, digesting, absorbing, excluding, and generating, in a new and ethereal element. Here, in the brain, is all the process of alimentation repeated, in the acquiring, comparing, digesting, and assimilating of experience. Here again is the mystery of generation repeated.”
—Ralph Waldo Emerson (1803–1882)
