2.7.4. Hardware Breakpoints

Hardware breakpoints allow you to set a breakpoint on instructions residing in nonvolatile memory, such as flash memory. The hardware breakpoint mechanism continuously monitors the processor’s current instruction address. If the instruction address matches the hardware breakpoint address, the JTAG debug module takes control of the processor.

Hardware breakpoints are implemented using the JTAG debug module’s hardware trigger feature.
