6.8 Flash Memory
The flash memory can be programmed through the JTAG port, Spy-Bi-Wire (SBW), 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 (Info A to Info 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 Info A to Info D can be erased individually, or as a group with the main memory segments. Segments Info A to Info D are also called information memory.
- Segment A can be locked separately.
