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.
