PRODUCTION DATA.
The BSL enables programming of the FRAM or RAM using a UART serial interface (FRxxxx devices) or an I2C interface (FRxxxx1 devices). Access to the device memory through the BSL is protected by an user-defined password. Table 6-6 lists the BSL pin requirements. BSL entry requires a specific entry sequence on the RST/NMI/SBWTDIO and TEST/SBWTCK pins. For complete description of the features of the BSL and its implementation, see MSP430 Programming With the Bootloader (BSL).
