20.3 Block Configuration
Figure 20.5 shows the block configuration of 384-kbyte flash memory. Figure 20.6 shows the
block configuration of 256-kbyte flash memory. Figure 20.7 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 384-kbyte flash memory is divided into 4
kbytes (8 blocks), 32 kbytes (1 block), and 64 kbytes (5 blocks). The 256-kbyte flash memory is
divided into 4 kbytes (8 blocks), 32 kbytes (1 block), and 64 kbytes (3 blocks). The 128-kbyte
flash memory is divided into 1 kbyte (4 blocks), 16 kbytes (1 block), 28 kbytes (1 block), 8 kbytes
(2 blocks), and 32 kbytes (2 blocks). Erasing is performed in these units. Programming is
performed in 128-byte units starting from an address with lower eight bits H'00 or H'80.
