Type
I Multiplexed Cb, Y, and Cr digital video input bus.
I/O In Slave Mode (MSTR pin is low) Horizontal Synch input. In Master
Mode (MSTR pin is high) Horizontal Synch output.
I/O In slave mode (MSTR pin is low) Vertical Sync input. In master mode
Vertical Sync output.
I Master Mode;
If this pin is high, the chip outputs horizontal and vertical sync signals.
Otherwise it receives both horizontal and vertical sync signals.
I Select either component or composite video output.
0: Simultaneous Composite and S-Video output.
1: Component video output either RGB or YCbCr determined by the
register CR0[5:4].
1 Pedestal enable pins.
When this pin is high 7.5 IRE is added for the NTSC composite analog
output.
O Analog video output
Determined by the state of CPNT pin and CR0[5:4]

I/O Voltage reference. It has an internal voltage reference circuit, but may
be overridden by an external voltage reference input. A 0.1 uF ceramic
capacitor is required between this pin and GND.
I A resistor should be connected between this pin and GND to control the
DAC output current. The recommended value is 198 (382) ohm 1%
metal film resistor for double (single) end 75 ohm termination.
I Compensation capacitor for the DAC internal reference amplifier. A 0.1
uF ceramic capacitor is required between this pin and VDDA.
I/O DAC bias voltage. A 0.1 uf ceramic capacitor must be used to de-
couple this pin to VDDA.
