SLASEK0A December 2017 – March 2018 MSP430FR5969-SP
PRODUCTION DATA.
The BSL enables users to program the FRAM or RAM using a UART serial interface (FRxxxx devices). Access to the device memory through the BSL is protected by an user-defined password. Table 5-7 list the BSL pins 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 Programming With the Bootloader (BSL).
