Block Configuration

Figure 19.5 shows the block configuration of 256-kbyte flash memory. The thick lines indicate
erasing units, the narrow lines indicate programming units, and the values are addresses. The flash
memory is divided into 4 kbytes (eight blocks), 32 kbytes (one block), and 64 kbytes (three
blocks). Erasing is performed in these divided units. Programming is performed in 128-byte units
starting from an address whose lower eight bits are H'00 or H'80.
