23.3.2 Block Configuration of 128-Kbyte Flash Memory

Figure 23.6 shows the block configuration of 128-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 32 kbytes (2 blocks), 8 kbytes (2 blocks), 16 kbytes (1 block), 28 kbytes (1

block), and 1 kbyte (4 blocks). Erasing is performed in these divided units. Programming is

performed in 128-byte units starting from an address whose lower bits are H'00 or H'80.
