19.3 Block Configuration
Figure 19.5 shows the block configuration of 384-kbyte flash memory. The thick lines indicate
erasing units, the narrow lines indicate programming units, and the values are addresses. The 384-
kbyte flash memory is divided into 64 kbytes (5 blocks), 32 kbytes (1 block), and 4 kbytes (8
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.
