17.3 Block Configuration
Figure 17.5 shows the block configuration of 128-kbyte flash memory in the HD64F2218,
HD64F2218U, HD64F2218CU, HD64F2212, HD64F2212U and HD64F2212CU. 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.
