O Output pins for grid signals for driving VF display tube (grid).

I Serial data input pin (positive logic).

I Shift clock input pin.

Serial data shifts at the rising edge of CLOCK.

I RC oscillator connecting pins. Oscillation frequency is 3.2MHz.

Connect a resistor between the OSC1 and OSC0 pins and a capacitor between

O the OSC0 pin and the ground.

I Chip select input pin. Data transfer is inhibited when this pin is "H".

Power supply pins. When using these pins, connect each of them to the power

— supply.

— Ground pin.
