The MSP low-power microcontrollers support the 2-wire SBW interface. SBW can be used to interface with MSP development tools and device programmers. Table 9-7 lists the SBW interface pin requirements. For further details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's Guide. For details on using the SBW interface, see the MSP430 Programming With the JTAG Interface User's Guide.
