19.3
Figure 19.5 shows the block configuration of 256-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 64 kbytes (3 blocks), 32 kbytes (1 block), and 4 kbytes (8 blocks). 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.
