(7) [Autoprocedure [EPV]] menu
The EPV command compares the checksum value when the user program is downloaded with the
checksum value in the user program area of the PG-FP4 subject to EPV. If the two values are the
same, it sequentially executes the Erase and Program commands explained above.
When the Program command is executed, whether the write level is secured is verified after the program has
been written. Note, however, that this verification does not detect a communication error of the user program
that is transmitted from the PG-FP4 to the target device.
To transmit the memory contents of the PG-FP4 to the target device to compare them with the data written to
the flash memory of the target device because a communication error of the user program was detected,
specify automatic execution of the Verify command after execution of the Program command, by using the
Command options on the Advanced tab of the [Device] > [Setup...] menu.
During EVP, the progress is displayed in the communication log window, indicating the operation of the
programmer. For the selected command, and its execution operation and message, refer to CHAPTER 5
SAMPLE PROGRAMMING SESSION USING GUI SOFTWARE.
You may abort the EPV procedure by pressing the Cancel button on the PG-FP4.
After completing the EPV command, the GUI software displays the target device command execution result.
(8) [Signature read] menu
The Signature Read command is used to read the signature information of the target device (such as the
device name and flash memory information).
(9) [Setup...] menu
The [Setup...] menu is used to perform flash memory writing settings in accordance with the user
environment, and command option settings. Each time the GUI software is started, the parameter
file (.PRM) and customized setup file (.SET) that were used last are read, and their setting contents are
displayed. On the [Setup...] menu, settings can be changed in accordance with the user environment, except
for the parameters that are dimmed. In addition, new settings can be saved to the customized setup file (the
data of the parameter file cannot be changed).
(a) Parameter file and customized setup file
The parameter file and customized setup file have the setting information necessary for rewriting the flash
memory of the target device.
• Parameter file
This file stores the timing and parameter data necessary for rewriting the flash memory of the target
device. Do not change the data of the parameter file as it guarantees the rewrite data.
The parameter file is protected by a checksum. If the checksum is illegal, the PG-FP4 does not accept
the parameter file.
• Customized setup file
Save the values of settings that have been made in accordance with the user environment to the
customized setup file after downloading the parameter file. The customized setup file saves the settings
of the [Setup...] menu, including the corresponding parameter file name, so that a new environment can
be set by downloading the customized setup file when the environment is started next time.
(b) Standard setup
This menu is used to set the rewriting environment of the target device's flash memory.
The mode of communication with the target device and the operating clock of the device differ depending
on the device used. For details, refer to the manual of the device used.
The following window opens.
