First, set the INH pin low at the same time as power is applied to turn off the display. This will set the S1/P1 to S12/P12 S12/P12, S13 to S51, and COM1 to COM4 pins low. While the INH pin is held low, the microcontroller should send the serial data. Finally, the application can set the INH pin to high. (See Figure 3.) t1.Determined by value of C and R.
