MYSON

TECHNOLOGY

SSB

Serial interface enable. It is used to enable the serial data

and is also used to select the operation of I2C or SPI bus. If

this pin is left floating, I2C bus is enabled, otherwise the SPI

bus is enabled.

SDA

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.

SCK

Serial clock input. The clock-input pin is used to synchronize

the data transfer. It has an internal pull-up resistor.

RIN

Red video input. It is used for auto sizing measurement and

this signal is came from video pre-amp red output.

GIN

Green video input. It is used for auto sizing measurement and

this signal is came from video pre-amp green output.

BIN

Blue video input. It is used for auto sizing measurement and

this signal is came from video pre-amp blue output.

No connection.

PWM0

Open-Drain PWM D/A converter 0. The output pulse width is

programmable by the register of Row 15, Column 23.

PWM1

Open-Drain PWM D/A converter 1. The output pulse width is

programmable by the register of Row 15, Column 24.

PWM2

Open-Drain PWM D/A converter 2. The output pulse width is

programmable by the register of Row 15, Column 25.

PWM3

Open-Drain PWM D/A converter 3. The output pulse width is

programmable by the register of Row 15, Column 26.

PWM4

Open-Drain PWM D/A converter 4. The output pulse width is

programmable by the register of Row 15, Column 27.

VDD

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.

VFLB

Vertical input. This pin is used to input the vertical synchroniz-

ing signal. It is leading triggered and has an internal pull-up

resistor.

INT

Intensity color output. 16-color selection is achievable by

combining this intensity pin with R/G/B output pins.

FBKG

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.

BOUT

Blue color output. It is a blue color video signal output.

GOUT

Green color output. It is a green color video signal output.

ROUT

Red color output. It is a red color video signal output.

VSS

Digital ground. This ground pin is used to internal digital cir-

cuitry.
