In addition to the standard JTAG interface, the CC430 family supports the two wire Spy-Bi-Wire interface. Spy-Bi-Wire can be used to interface with MSP430 development tools and device programmers. Table 6-5 lists the Spy-Bi-Wire interface pin requirements. For further details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's Guide. For a complete description of the features of the JTAG interface and its implementation, see MSP430 Programming With the JTAG Interface.
