10. INH and Display Control

Since the LSI internal data (D1 to D156, DR, SC, and BU) is undefined when

power is first applied, then display is off(SEG1 to SEG52,COM1 to COM3=low)

by setting the INH pin low at the same time as power is applied.Then meaningless

display at the power-on can be prevented by transferring serial data from the

controller while the display is off and setting INH pin high after the transfer completes.
