7.1
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 56-kbyte flash
memory is divided into 1 kbyte × 4 blocks, 28 kbytes × 1 block, 16 kbytes × 1 block, and 8 kbytes
× 1 block, while the 32-kbyte one is into 1 kbyte × 4 blocks and 28 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.

 The flash memory is programmed 128 bytes at a time. Erase is performed in single-block
 The flash memory can be reprogrammed up to 1,000 times.
 On-board programming/erasing can be done in boot mode, in which the boot program built
 Flash memory can be programmed/erased in programmer mode using a PROM
 For data transfer in boot mode, this LSI's bit rate can be automatically adjusted to match
 Sets software protection against flash memory programming/erasing.
 Operation of the power supply circuit can be partly halted in subactive mode. As a result,
units. The 56-kbyte flash memory for H8/36077F is configured as: 1 kbyte × 4 blocks, 28
kbytes × 1 block, 16 kbytes × 1 block, and 8 kbytes × 1 block, while the 32-kbyte one for
H8/36074F is as: 1 kbyte × 4 blocks and 28 kbytes × 1 block. To erase the entire flash
memory, each block must be erased in turn.
