CHAPTER 5 COMMAND REFERENCE

5.3.5 E.P.V.
The [E.P.V.] command makes a blank check. If the result is OK, the [Program] command is executed. If the check
finds an error, the [Erase] command and [Program] command are executed in that order.
When writing a delivered device for a second or subsequent time, use this command.
If the user does not know whether the device has been erased, use this command to write the device.
Execute this command by selecting [E.P.V.] from the [Procedure] pull-down menu or by clicking the
button on the operation screen.
While the command is being executed, the progress is displayed in the log window. At the same time, the Erase,
Program, and Verify LEDs on the PG-FP3 light and the LED corresponding the command currently being executed
blinks.
The display in the log window is the same as that for each individual command.
The address range during command execution depends on the currently set mode (Chip, Block, or Area) and the
range setting condition. In CHIP mode, all space on the target is erased, programmed, or verified. In BLOCK and
AREA modes, only the specified address range is erased, programmed, or verified. When executing [E.P.V.] in a mode
other than CHIP, therefore, you must specify an address range.
Caution Avoid using this command for the device erased by the [Erase] command. The blank check level
of the [E.P.V.] command is the same as that of the [Erase] command. Even if the device has been
erased, the blank check by this command would detect an error, owing to voltage fluctuations in
operation. If this occurs, the device would be erased again.
5.3.6 Chip set/Block set/Area set
[Chip set/Block set/Area set] selects an operating mode. The display for the command changes depending on the
condition of the current mode.
Some devices do not have segment modes such as BLOCK and AREA, or only have one or the other of the
modes. Any mode not available to the device is not displayed.
The following explanation assumes that a device with all of the modes (CHIP, BLOCK, and AREA) is being used.
Execution of a command is always started in CHIP mode, and the mode changes as follows each time a command
has been executed.
CHIP → BLOCK �� AREA → CHIP …
At the same time, the command display and the button display on the operation screen change.
Before executing the Chip set/Block set/Area set command, load the parameter file. Before executing the
command, check that the target device is connected. When the command is executed, the application addresses the
device according to the parameter file information and device signature information.
If the parameter file is not loaded or if the target device is not connected, correct addressing may not be performed,
resulting in a malfunction.
Execute this command to change the mode by selecting [Chip set/Block set/Area set] from the [Procedure] pull-
down menu or by clicking the , , or button on the operation screen.
