RES and the Display Controller
Since the LSI internal data (D1 to D90 and the control data) is undefined when power is first applied, the output pins
S1/P1 to S4/P4, S5 to S43, COM1, COM2, KS1/S44 and KS2/S45 should be held low by setting the RES pin low at the
same time as power is applied. Then, meaningless displays at power on can be prevented by transferring data from the
controller and setting RES high when that transfer has completed.
