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 5. BSL entry requires a specific entry sequence on the RST/NMI/SBWTDIO and TEST/SBWTCK
pins. For further details on interfacing to development tools and device programmers, see the MSP430 Hardware
Tools User's Guide (SLAU278). For complete description of the features of the BSL and its implementation, see
MSP430 Programming Via the Bootstrap Loader (SLAU319).

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 6. 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).
