qVersion Information Output Command
This command outputs the version information of the control pro-
gram stored in the Boot ROM 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 on-
ward.
This data is composed of 8 ASCII code characters.

qBoot ROM Area Output Command
This command reads the control program stored in the Boot ROM
area in page (256 bytes) unit. Execute the Boot ROM area output
command as explained here following.
(1) Transfer the “FC16” command code with the 1st byte.
(2) Transfer addresses AB8 to AB15 and AB16 to AB23 with the 2nd
and 3rd bytes respectively.
(3) From the 4th byte onward, data (DB0 to DB7) for the page (256
bytes) specified with addresses AB8 to AB23 will be output se-
quentially from the smallest address first synchronized with the
fall of the clock.
