In addition to the standard JTAG interface, the MSP430 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 6-6 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 complete description of the features of the JTAG interface and its implementation, see the MSP430 Memory Programming With the JTAG Interface.
