Version Information 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.

(1) Transfer the “FB16” command code with the 1st byte.

(2) The version information will be output from the 2nd byte onward. This data is composed of 8

ASCII code characters.

Boot ROM Area Output Command

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.

(1) Transfer the “FC16” command code with the 1st byte.

(2) Transfer addresses A8 to A15 and A16 to A23 with the 2nd and 3rd bytes respectively.

(3) From the 4th byte onward, data (D0–D7) for the page (256 bytes) specified with addresses A8 to

A23 will be output sequentially from the smallest address first.
