The features of the 12-kbyte (including 4 kbytes as the E7 or E8 control program area) flash
memory built into the HD64F36912G and HD64F36902G are summarized below.
7.1
Figure 7.1 shows the block configuration of 12-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 1 kbyte 4 blocks and 4 kbytes 2 blocks. Erasing is performed in these
units. Programming is performed in 64-byte units starting from an address with lower eight bits
H'00, H'40, H'80, or H'C0.

Programming/erase methods
Reprogramming capability
On-board programming
Automatic bit rate adjustment
Programming/erasing protection
The flash memory is programmed in 64-byte units at a time. Erase is performed in single-
block units. The flash memory is configured as follows: 1 kbyte 4 blocks and 4 kbytes
2 blocks. To erase the entire flash memory, each block must be erased in turn.
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
into the chip is started to erase or program of the entire flash memory. In normal user
program mode, individual blocks can be erased or programmed.
For data transfer in boot mode, this LSI's bit rate can be automatically adjusted to match
the transfer bit rate of the host.
Sets software protection against flash memory programming/erasing.
