For many applications, programming a microcontroller after it has been soldered to the circuit board in the target application is more convenient than using a separate programmer. With the Texas Instruments MSP430F11x1, this can be done quite easily using the JTAG pins.
The Flash Emulation Kit makes it very easy to develop programs for the MSP430, debug the programs and program them into the microcontroller. However, prototype testing usually reveals a need for minor improvements to the software. The MSP430 has a JTAG port that can be enabled by applying a High level to the TEST pin.
