SLAS703C April 2010 – September 2020 MSP430BT5190
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. The Spy-Bi-Wire interface pin requirements are shown in Table 8-5. For further details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's Guide (SLAU278). For a complete description of the features of the JTAG interface and its implementation, see MSP430 Programming Via the JTAG Interface (SLAU320).
