摘要:The MSP430 bootstrap loader (BSL) enables users to communicate with embedded memory in the MSP430 microcontroller during the prototyping phase, final production, and in service. Both the programmable memory (flash memory) and the data memory (RAM) can be modified as required.
   The commonly used UART protocol with RS232 interfacing is supported, allowing flexible use of both hardware and software.
   To use the bootstrap loader, a specific BSL entry sequence has to be applied to specific device pins. An added sequence of commands initiates the desired function. A boot-loading session can be exited by continuing operation at a defined user program address or by the reset condition. Access to the MSP430 memory via the bootstrap loader is protected against misuse by a user-defined password.
