The BSL lets users program the FRAM or RAM using a UART interface. Access to the device memory through the BSL is protected by an user-defined password. Table 6-4 lists the BSL pin requirements. 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 the MSP430 FRAM Device Bootloader (BSL) User's Guide.
