INH and Display Control

Since the LSI internal data (D1 to D54 and control data) is undefined when power is first applied, the display is turned

off (S1 to S27, COM1 and COM2 = low) by setting INH pin low at the same time as power is applied. Then, meaningless

display at the power on can be prevented by transferring all 80 bits of serial data from the controller while the display is

turned off and INH pin high after the transfer completes. (See Figure 3.)
