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.
