Digital power supply. Positive 5 V DC supply for internal digi-
- 9 13 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-
I 10 14 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-
O 12 16 nals of VGA while this chip is displaying characters or win-
dows.
O 13 17 Blue color output. It is a blue color video signal output.
O 14 18 Green color output. It is a green color video signal output.
O 15 19 Red color output. It is a red color video signal output.

Digital ground. This ground pin is used to internal digital cir-
cuitry.
3.0 FUNCTIONAL DESCRIPTIONS
3.1 SERIAL DATA INTERFACE
The serial data interface receives data transmitted from an external controller. And there are 2 types of bus
can be accessed through the serial data interface, one is SPI bus and other is I2C bus.
3.1.1 SPI bus
While SSB pin is pulled to "high" or "low" level, the SPI bus operation is selected. And a valid transmission
should be starting from pulling SSB to "low" level, enabling MTV038 to receiving mode, and retain "low" level
until the last cycle for a complete data packet transfer. The protocol is shown in Figure 1.
