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.

Data Transmit

13 - P1.1

Data Receive

22 - P2.2

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 two segments of information memory (A and B) of
128 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 and B can be erased individually, or as a group with segments 0 to n.
Segments A and B are also called information memory.

D

New devices may have some bytes programmed in the information memory (needed for test during
manufacturing). The user should perform an erase of the information memory prior to the first use.

MSP430F169 and MSP430F1612 flash segment n = 256 bytes.
