Bias supply voltage pins to drive the LCD. Use an external bias voltage supply for driving the
LCD.
DO
Shift register output pin. The data which was input from DI is output from DO with 32 bits
delay, synchronized with the clock pulse. The MSM5238 is used at 1/32 duty and also at 1/64
duty through cascade connection. Refer to Figure 1 below.
