FD1000A
3/4COM LCD Driver
INH Pin and Display Control
Since the FD1000A internal data (the display data D1 to D156/D204 and the control data) is
undefined when power is first supplied, the display is off (SEG1 to SEG52 and COM1 to COM3=Low)
By setting the INH\ pin low at the same time as power is supplied.
While the INH\ pin is held low, the micro-controller should send the serial data and set INH\ pin
high after the transfer completes.
