bootstrap loader (BSL)
The BSL enables users to program the flash memory or RAM using a UART serial interface. Access to device
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.

flash memory, flash
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:
D 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.
D Segments 0 to n may be erased in one step, or each segment may be individually erased.
D 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.
D Segment A might contain calibration data. After reset, segment A is protected against programming or
erasing. It can be unlocked but care should be taken not to erase this segment if the calibration data is
required.
