Flash Memory
The flash memory can be programmed via the Spy-Bi-Wire/JTAG port 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:
• 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.
