The BSL enables users to program the flash memory or RAM using a UART serial interface. Access to the device memory by the BSL is protected by an user-defined password. The BSL requires a specific entry sequence on the RSTDVCC/SBWTDIO and TEST/SBWTCK pins. Table 6-3 lists the required pins and their functions. For 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 BSL and its implementation, see the MSP430 Flash Device Bootloader (BSL) User's Guide.
Devices from TI come factory programmed with the timer based UART BSL only. If the USCI based BSL is preferred, it is also available, but must be programmed by the user.
