The LCD segments corresponding to COM2 is on.

The LCD segments corresponding toCOM1 and COM2 are on.

The LCD segments corresponding to COM3 is on.

The LCD segments corresponding to COM1 and COM3 are on.

The LCD segments corresponding to COM1 to COM3 are on

INH and display control

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

off (S1 to S52, COM1 to COM3= low) by setting the INH pin low at the same 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.(see figure3).
