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. BSL Function PZ Package Pins Data Transmit 87 - P1.0 Data Receive 86 - P1.1 flash memory, Flash_A 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−n. Segments A to D are also called information memory. D Segment A contains 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. |
