7.1 Block Configuration
Figure 7.1 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
flash memory is divided into 1 kbyte × 4 blocks and 28 kbytes × 1 block. 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.
