Embedded Emulation, a common software and physical interface used in all MSP430s, results in only one tool that needs to be learned for any device in the family. The Flash Emulation Tool – or FET – is a complete JTAG based real-time emulation device. The FET comes with a universal USB JTAG interface (a parallel port JTAG interface is also available), a target board, cables and all documentation on a CD-ROM. Stand alone debugging and programming interfaces without a target board (MSP-FET430UIF) are also available. All USB FETs include support for both the standard 4-wire JTAG and 2-wire Spy Bi-Wire.
