3.0 FUNCTIONAL DESCRIPTIONS
3.1 Serial Data Interface
The serial data interface receives data transmitted from an external controller. There are 2 types of bus
which can be accessed through the serial data interface: SPI bus and I
2
C bus.
3.1.1 SPI Bus
When the SSB pin is pulled to a HIGH or LOW level, the SPI bus operation is selected. A valid trans-
mission should start from pulling SSB to LOW level, enabling the MTV118 receiving mode and retaining
the LOW level until the last cycle for a complete data packet transfer. The protocol is shown in Figure 1
on page 4.
There are 3 transmission formats as shown below:

Open-Drain PWM D/A Converter 3.
The output pulse width is
programmable by the register of row 15, column 22.
Open-Drain PWM D/A Converter 4.
The output pulse width is
programmable by the register of row 15, column 23.
Open-Drain PWM D/A Converter 5.
The output pulse width is
programmable by the register of row 15, column 24.
Open-Drain PWM D/A Converter 6.
The output pulse width is
programmable by the register of row 15, column 25.
Open-Drain PWM D/A Converter 7.
The output pulse width is
programmable by the register of row 15, column 26.
Power Supply.
Positive 5 V DC supply for internal circuitry and a
0.1uF decoupling capacitor should be connected across VDD and
VSS.
Vertical Input.
This pin is used to input the vertical synchronizing
signal. It is triggered by lead and has an internal pull-up resistor.
Half Tone Output / PWM Clock Output.
This is a multiplexed pin
selected by the PWMCK bit. This pin can be a PWM clock or used
to attenuate R, G, B gain of VGA for the transparent windowing
effect.
Fast Blanking Output.
It is used to cut off external R, G, B sig-
nals of VGA while this chip is displaying characters or windows.
Blue Color Output.
This is a blue color video signal output.
Green Color Output.
This is a green color video signal output.
Red Color Output.
This is a red color video signal output.
Ground.
This ground pin is used for internal circuitry.
