 Verify in the MCU
Data will be sent to the MCU with a verify command, and the target device will perform verification.
Since the range of comparison may be extended depending on the specifications of the verify
command, a verify error may occur if filling of 0xFF is not performed. Use this option if the execution of
read commands is disabled by the security settings of the target device.
• Skip ID Code Verify
In general, do not select the check box when this feature is displayed as an option. However, use this
feature in cases of the following type.
The security settings of the MCU may make reading of the ID code impossible since the ID code in the
MCU is protected. This may lead to an error in verification processing. To avoid errors of this type, select
this check box to use the feature.
For details, refer to section 13.8, Verification after Protecting the MCU.
(D) Checksum Option
Select the method for calculation when "Checksum" is selected under "Command". Usable methods vary
with the target device.
• Calculate all areas
In general, the range for calculation of the checksum is selected as all ranges of the target device or the
range specified on the [Block Settings] tabbed page.
(E) Fill with 0xFF
Select this check box if you wish to fill the ranges that do not contain program file data with 0xFF.
Target areas: Code flash and user-boot areas or data flash area
• When "Fill with 0xFF" is selected
 Programming: 0xFF will be written to the ranges that do not contain program file data.
 Verification: The ranges that do not contain program file data will be compared with 0xFF as the
expected value.
• When "Fill with 0xFF" is not selected
 Programming: No data will be written to the ranges that do not contain program file data.
 Verification: The ranges that do not contain program file data will not be verified.
Remark: "Fill with 0xFF" cannot be deselected for some target devices.
Caution: Even if "Fill with 0xFF" is not used, filling of 0xFF is always performed in the minimum unit of
programming by the MCU.
