Accepts positive polarity Vsync input.
= 0
Accepts negative polarity Vsync input.
PWM1, PWM0 - Selects the PWMCK output frequency.

XIN frequency /1
The initial value is 0, 0 after power-up.
Notes :
When XIN is not present, don't write data in any address. If data is written in any address, a
malfunction may occur.
3.10 PWM D/A Converter
There are 8 open-drain PWM D/A outputs (PWM0 to PWM7). The PWM D/A converter output pulse
width is programmable by writing data to columns 19-26 registers of row 15 with 8-bit resolution to con-
trol the pulse width duration from 0/256 to 255/256. The sampling rate is selected by PWM1, PWM0 as
shown in table 4. In applications, all open-drain output pins should be pulled up by external resistors to
supply voltage (5V to 9V) for the desired output range.
ROW 15
PWMDA0 - PWMDA7 - Defines the output pulse width of pins PWM0 to PWM7.
3.11 Color Encoder
The decoder generates the video output to ROUT, GOUT and BOUT by integrating window color, bor-
der blackedge, luminance output and color selection output (R, G, B) to form the desired video outputs.
