Block Configuration

Figure 6.8 shows the block configuration of the flash memory. The thick lines indicate erasing
units, the narrow lines indicate programming units, and the values are addresses. In versions with
32 Kbytes of flash memory, the flash memory is divided into 1 Kbyte × 4 blocks and 28 Kbytes ×
1 block. In versions with 16 Kbytes of flash memory, the flash memory is divided into 1 Kbyte × 4
blocks and 12 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.
