Block Configuration

Figure 7.1 shows the block configuration of flash memory. The thick lines indicate erasing units,

the narrow lines indicate programming units, and the values are addresses. The 96-kbyte flash

memory is divided into 1 kbyte

× 4 blocks, 28 kbytes × 1 block, 16 kbytes × 2 blocks, and 32

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.
