6.5.3 Block Configuration
Figure 6.8 shows the block configuration of 32-kbyte flash memory. The thick lines indicate
erasing units, the narrow lines indicate programming units, and the values are addresses. The 32-
kbyte flash memory is divided into 1 kbyte × 4 blocks and 28 kbytes × 1 block. Erasing is
performed in these units. The 16-kbyte flash memory is divided into 1 kbyte × 4 blocks and 12
kbytes × 1 block. Programming is performed in 128-byte units starting from an address with lower
eight bits H'00 or H'80.
