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:
•
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.
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.
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.
