After the required commands and display data are entered, perform busy detection
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.
