Version Information Output Command
Boot ROM Area Output Command
This command outputs the version information of the control program stored in the boot area. Execute
the version information output command as explained here following.
This command outputs the control program stored in the boot ROM area in one page blocks (256
bytes). Execute the boot ROM area output command as explained here following.
