23.3 Block Configuration
23.3.1 Block Configuration of 64-Kbyte Flash Memory
Figure 23.5 shows the block configuration of 64-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 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.
