PRODUCTION DATA.
The MSP low-power microcontrollers support the standard JTAG interface, which requires four signals for sending and receiving data. The JTAG signals are shared with general-purpose I/O. The TEST/SBWTCK pin enables the JTAG signals. In addition to these signals, the RST/NMI/SBWTDIO is required to interface with MSP430 development tools and device programmers. Table 6-5 lists the JTAG 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 JTAG interface, see MSP430 Programming With the JTAG Interface.
