This pin is used for enabling or disabling the built-in oscillation
circuit for the display clock.
CL = HIGH: Built-in oscillation circuit is enabled.
CL = LOW: Built-in oscillation circuit (external input) is disabled.
Select CL = LOW to turn the external clock off.
When using the built-in oscillation circuit, select CL = HIGH (V
a given combination of display RAM data and internal FR signal.
These pins output the signal for the common drive of LCD.
Following number of pins are assigned to S1D15A06
One of V
a given combination of scan data and FR signal.
They are COM pins exclusively used for the indicator.
Both pins output the same signal.
They must be made open when not used.
These are terminals for IC chip testing. They are set to OPEN.
These pins output the signal for the segment drive of LCD.
