flash memory
The flash memory can be programmed via the JTAG port, the bootstrap loader, 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:
D Flash memory has n segments of main memory and two segments of information memory (A and B) of 128
bytes each. Each segment in main memory is 512 bytes in size.
D Segments 0 to n may be erased in one step, or each segment may be individually erased.
D Segments A and B can be erased individually, or as a group with segments 0n.
Segments A and B are also called information memory.
D New devices may have some bytes programmed in the information memory (needed for test during
manufacturing). The user should perform an erase of the information memory prior to the first use.
