CHAPTER 2 BASIC FORMAT
2.5 Setup Processing for Oscillation Frequency and Erase Time
After the synchronization processing with the
μ
PD75F4264 has been completed, the operating frequency and
erase time settings must be sent to the
μ
PD75F4264. For description of erase times, see

PROGRAMMING CHARACTERISTICS (PRELIMINARY)
.
2.6 Write Processing
The following three commands are the basic commands used for writing to the
μ
PD75F4264.
(1) Erase command
This command is used to erase the
μ
PD75F4264’s flash memory.
(2) Write command
This command is used to write to the
μ
PD75F4264’s flash memory and EEPROM. There are two types of
write commands, which provide different levels of efficiency during the write operation.
High-speed write command
This command performs the write operation for write sizes ranging from 1 to 16 bytes or the specified write
address
Note
.
Continuous write command
This command performs the write operation for a write size specified by the high-speed write command.
Data is written to the next address after the address last written to by either the high-speed write command
or the continuous write command.
Note
A one-byte write size (00H to 10H) can be combined with a three-byte write address (000000H to
000FFFH). Hereafter, this combination is referred to as 4-byte data.
(3) Verify command
This command is used to verify the contents of the
μ
PD75F4264’s flash memory and the contents of data sent
from the flash writer.
In addition to the basic commands described above, there are also the following four types of commands.
(1) Blank check command
This command is used to confirm that the
μ
PD75F4264’s flash memory has been erased.
(2) Read command
This command is used to read the contents of the
μ
PD75F4264’s EEPROM. There are two types of read
commands, which provide different levels of efficiency during the read operation.
High-speed read command
This command performs the read operation for read sizes ranging from 1 to 16 bytes or the specified read
address (4-byte data).
Continuous read command
This command performs the read operation for a read size specified by the high-speed read command. Data
is read from the next address after the address last read by either the high-speed read command or the
continuous read command.
