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 MSP430 Programming Via the Bootstrap
Loader User’s Guide (

Flash Memory
The flash memory can be programmed via the JTAG port, the bootstrap loader, or in-system by the CPU. The
CPU can perform single-byte and single-word writes to the flash memory. Features of the flash memory include:
•
CPU can perform single-byte and single-word writes to the flash memory. Features of the flash memory include:
•
Flash memory has n segments of main memory and four segments of information memory (A to D) of
64 bytes each. Each segment in main memory is 512 bytes in size.
64 bytes each. Each segment in main memory is 512 bytes in size.
•
Segments 0 to n may be erased in one step, or each segment may be individually erased.
•
Segments A to D can be erased individually, or as a group with segments 0 to n.
Segments A to D are also called information memory.
Segments A to D are also called information memory.
•
Segment A contains calibration data. After reset, segment A is protected against programming and erasing. It
can be unlocked, but care should be taken not to erase this segment if the device-specific calibration data is
required.
