bootstrap loader (BSL)

The MSP430 bootstrap loader (BSL) enables users to program the flash memory or RAM using a UART serial

interface. Access to the MSP430 memory via the BSL is protected by user-defined password. For complete

description of the features of the BSL and its implementation, see the Application report Features of the MSP430

Bootstrap Loader, Literature Number SLAA089.
