PRODUCTION DATA.
The MSP430 family supports 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 is used to enable the JTAG signals. In addition to these signals, the RSTDVCC/SBWTDIO is required to interface with MSP430 development tools and device programmers. The JTAG pin requirements are shown in Table 6-5. 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. Additional information can be found in Designing With MSP430F522x and MSP430F521x Devices.
NOTE
NOTE
On other MSP430 devices, the RST/NMI pin has been used for SBWTDIO, so care must be taken not to mistakenly use the incorrect pin. On the F522x and F521x series of devices, RSTDVCC is used for SBWTDIO as shown in Table 6-5. Additional information can be found in Designing With MSP430F522x and MSP430F521x Devices.
