18.3 Block Configuration
Figure 18.5 shows the block configuration of 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 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.
