Serial interface enable.
It is used to enable the serial data
and is also used to select the operation of I
2
C or SPI bus. If
this pin is left floating, I
2
C bus is enabled, otherwise the SPI
bus is enabled.
Serial data input.
The external data transfer through this pin to
internal display registers and control registers. It has an inter-
nal pull-up resistor.
Serial clock input.
The clock-input pin is used to synchronize
the data transfer. It has an internal pull-up resistor.
Red video input.
It is used for auto sizing measurement and
this signal is came from video pre-amp red output.
Green video input.
It is used for auto sizing measurement and
this signal is came from video pre-amp green output.
Blue video input.
It is used for auto sizing measurement and
this signal is came from video pre-amp blue output.
No connection.
Open-Drain PWM D/A converter 0.
The output pulse width is
programmable by the register of Row 15, Column 23.
Open-Drain PWM D/A converter 1.
The output pulse width is
programmable by the register of Row 15, Column 24.
Open-Drain PWM D/A converter 2.
The output pulse width is
programmable by the register of Row 15, Column 25.
Open-Drain PWM D/A converter 3.
The output pulse width is
programmable by the register of Row 15, Column 26.
Open-Drain PWM D/A converter 4.
The output pulse width is
programmable by the register of Row 15, Column 27.
Digital power supply.
Positive 5 V DC supply for internal digi-
tal circuitry and a 0.1uF decoupling capacitor should be con-
nected across to VDD and VSS.
Vertical input.
This pin is used to input the vertical synchroniz-
ing signal. It is leading triggered and has an internal pull-up
resistor.
Intensity color output.
16-color selection is achievable by
combining this intensity pin with R/G/B output pins.
Fast Blanking output.
It is used to cut off external R, G, B sig-
nals of VGA while this chip is displaying characters or win-
dows.
Blue color output.
It is a blue color video signal output.
Green color output.
It is a green color video signal output.
Red color output.
It is a red color video signal output.
Digital ground.
This ground pin is used to internal digital cir-
cuitry.
