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 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.
