Block Configuration

Figure 17.5 shows the block configuration of 128-kbyte flash memory in the HD64F2218,

HD64F2218U, HD64F2212, and HD64F2212U. The thick lines indicate erasing units, the narrow

lines indicate programming units, and the values are addresses. The flash memory is divided into

one kbyte (four blocks), 28 kbytes (one block), 16 kbytes (one block), eight kbytes (two blocks),

and 32 kbytes (two blocks). Erasing is performed in these divided units. Programming is

performed in 128-byte units starting from an address whose lower eight bits are H'00 or H'80.
