Version 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
FB
16
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.

Boot 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
FC
16
command code with the 1st byte.
(2) Transfer addresses AB
8
to AB
15
and AB
16
to AB
23
with the 2nd
and 3rd bytes respectively.
(3) From the 4th byte onward, data (DB
0
to DB
7
) for the page (256
bytes) specified with addresses AB
8
to AB
23
will be output se-
quentially from the smallest address first synchronized with the
fall of the clock.
