When the command is executed, the following dialog box opens, allowing you to set a communication port.

  • Page 57: Procedure

    5.3 Procedure When [Procedure] is clicked, the pull-down menu shown below is displayed. This menu lists commands that manipulate the target by erasing, programming, or verifying the target. 5.3.1 Download HEX [Download HEX] downloads the user program loaded into FLASHPRO3 with [Load File] to the PG-FP3. The progress of downloading is displayed in the log window.

  • Page 58: Erase

    5.3.2 Erase [Erase] erases the flash memory. Use this command to keep the device with the flash memory erased. To program the flash memory erased by this command, use the [Program] command. A device that has been just delivered to you is blank and can be programmed without having to be erased.

  • Page 59: Program

    5.3.3 Program The [Program] command writes the data sent from the writer into the flash memory. Then, the command verifies whether the write level is secured. Use this command when writing a delivered device for the first time or when writing a microcontroller kept with its flash memory erased.

  • Page 60

    The verification is made in either of the following two methods. The PG-FP3 automatically executes the verification in the method that matches the target device. <1> Re-sends the written data from the PG-FP3 and verifies the data written in the flash memory against the re-sent data.

  • Page 61: Verify

    5.3.4 Verify The [Verify] command sends the written data from the PG-FP3 and verifies the data written in the flash memory against the sent data. This command does not check the write level. Use this command to check whether data communication between the PG-FP3 and the microcontroller with flash memory has been normally performed.

  • Page 62: E.p.v

    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.
