The CPU can perform single-byte and single-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 64 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 contains calibration data. After reset, segment A is protected against programming and erasing. It can be unlocked, but care should be taken not to erase this segment if the device-specific calibration data is required.
