PRODUCTION DATA
The BSL can program 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 9-6 lists the pins that are required for use of the BSL. 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 Devices Bootloader (BSL) User's Guide. More information on the BSL can be found at www.ti.com/tool/mspbsl.
