Flash Memory

The flash memory can be programmed via the Spy-Bi-Wire or 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.
