PRODUCTION DATA.
The BSL lets users program the FRAM or RAM using either the UART serial interface or the I2C interface. Access to the MCU memory through the BSL is protected by an user-defined password. Use of the BSL requires four pins (see Table 6-3 and Table 6-4). BSL entry requires a specific entry sequence on the RST/NMI/SBWTDIO and TEST/SBWTCK pins. This device supports the blank device detection to automatically invoke the BSL, skipping this special entry sequence, to save time and simplify onboard programming. For a complete description of the features of the BSL, see the MSP430 FRAM Device Bootloader (BSL) User's Guide.
