* Set 0 Volt Vi(t) ≤ V_DD(t)
Here Vi(t), V_DD(t) indicate the transitive state of Vi, V_DD when power supply is
turned ON or OFF
Note 1: Please avoid floating state of interface signal at invalid period.
Note 2: When the interface signal is invalid, be sure to pull down the power supply
for LCD V_DD to 0V.
