The BSL lets users program the flash memory or RAM using a UART serial interface. Access to the device memory through the BSL is protected by an user-defined password. Table 6-3 lists the pins that are required to use the BSL. 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. For complete description of the features of the BSL and its implementation, see MSP430 Flash Device Bootloader (BSL) User's Guide.
