2 Setting value for pixel memory initialization
SCS=Driving accordingly to clear pixel internal memory method (use all clear flag or write all screen white)
S1=M2 (all clear flag) = “H” or write white
SCLK: Normal Driving
[Remark] Precaustions at ehte time of power on and power off.
Remark 1)When power on , VDDand VDDA are same timem or VDD should be faster than the VDDA.
Remark 2) When power off, VDD and VDDA are same time or VDDA shoud be faster than the VDD.
