Bootstrap Loader (BSL)
The BSL enables users to program the flash memory or RAM using a UART serial interface. Access to the
device memory via the BSL is protected by an user-defined password. Usage of the BSL requires four pins as
shown in Table 3. BSL entry requires a specific entry sequence on the RST/NMI/SBWTDIO and TEST/SBWTCK
pins. For complete description of the features of the BSL and its implementation, see the MSP430 Memory
Programming User's Guide, literature number SLAU265.

JTAG Operation
JTAG Standard Interface
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 RST/NMI/SBWTDIO is required to interface with MSP430
development tools and device programmers. The JTAG pin requirements are shown in Table 4. For further
details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's
Guide, literature number SLAU278.

Spy-Bi-Wire Interface
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 5. For further details on interfacing to development tools and
device programmers, see the MSP430 Hardware Tools User's Guide, literature number SLAU278.
