6.9 Flash Memory (Link to User's Guide)
The flash memory can be programmed by the JTAG port, Spy-Bi-Wire (SBW), the BSL, or in-system by
the CPU. The CPU can perform single-byte, single-word, and long-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
128 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.
• Segment A can be locked separately.
