Terminal Description
Pins for input of key data for key scan.
Key request output pin.
Goes "H" when one of the keys is pressed
{key data "H').
Pin for input of data shift clock.
Reads data at positive going and outputs
data at negative going.
Pin for input/output of data.
Inputs of commands and display data and
outputs key data.
The data is input from the significant bit at
positive going of the shift clock and output
from the significant bit at negative going
of the shift clock.
This pin is open drain during output.
Pin for input of strobe signal.
"L" enables data input. Command is
processed at the positive going.
Q

> o
Pin for switching between LCD and LED.
"H makes SEGn/LEDn LCD segment outputs
and "L" makes them LED driver outputs.
Pin for input of Output Enable signal.
"L’ turns all segments and all LEDs off.
Connect the resistor of oscillator circuit.
