The BSL enables users to 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. Use of the BSL requires four pins (see Table 6-3). BSL entry requires a specific entry sequence on the RST/NMI/SBWTDIO and TEST/SBWTCK pins. For a complete description of the features of the BSL and its implementation, see MSP430 Programming With the Bootloader (BSL). For further details on interfacing to development tools and device programmers, see the MSP430 Hardware Tools User's Guide.
