(3) MODE1 = L, MODE2 = L
All output always become Hi-Z condition during STB = H in this mode. And output short function works at the falling
edge of STB during requested period by MODE3. At MODE3 = H, the driver IC counts 34 CLKs of output short period
by itsself, and count 68 CLKs at MODE = L. After finishing the output short period, the gray-scale voltage to the LCD
panel is started. When POL signal is not changed, the gray-scale voltage to the LCD panel is started at the falling edge
of STB without any change of POL signal (See figure 8−3).
