command set

LOT, I1="1", I0="1"

AINC executed 48 times

Make the SO output enable, to perform busy detection.

Input a wait for the SOE/D command processing. (For the processing

of each command after this, perform busy detection. *1)

Set the blink pattern and bank change mode.

Set the Load Option. (Blank-code writing and blink-cancellation

based on the SO pin status. When it is confirmed that the status has been changed

from BUSY (SO="L") to NON-BUSY (SO="H"), enter the next data.

If busy detection is not performed, wait for 10 master oscillation clocks when used at

1/17 duty or for 20 master oscillation clocks when at 1/9 duty, then enter the next

data.
