Applications operating at lower power, with smaller packaging and higher-precision, benefit greatly from the MSP430’s embedded emulation. No external emulator is required as the device emulates itself. JTAG is used to communicate unobtrusively with the MSP430 in an application. This means that all development is done under the same conditions that will be seen in the final product. Using embedded emulation, projects are developed faster, with fewer errors, and at a lower cost.
