When INHb = low (VSS), Display forced off
S1/P1/G1 to S6/P6/G6 = low (VSS)
S7 to S69 = low (VSS)
COM1 to COM4 = low (VSS)
Stop the LCD drive bias voltage generation divider
resistors.
Stop the internal oscillation circuit.
When INHb = high (VDD), Display on
However, serial data transfer is possible when the display is
forced off.
