Preliminary data sheet
2.7.6 Auxiliary Pins
8-bit Mode:
6-bit Mode:
Double D1 Mode
In this mode, twenty video data pins are used out of the 30. These twenty pins are
used to stream out one video data stream. QVCP outputs YUV 4:2:2 by splitting Y
and UV into two separate streams, Y uses 10 pins and the interleaved UV uses the
other 10 pins. The data stream can be generated by splitting up the QVCP into two
sets of layers.
10-bit Mode:
8-bit Mode:
6-bit Mode:
QVCP has two auxiliary (AUX) output pins, each of which can be independently
programmed for:
The two auxiliary are referenced as QVCP_AUX (QVCP auxiliary 1) and VDO_AUX
(QVCP auxiliary 2) in
1. Composite blanking, where the value on the pin is asserted HIGH (1) if either
2. Odd/even indication, where the field polarity is indicated in the interlaced mode.
3. Video/graphics indication, where the color keyn (n = 1, 2, 3, 4) of the mixer 2 is

Vblanking is TRUE or Hblanking is TRUE or both are TRUE. The complement of
the value on the pin can, therefore, be used as the indicator of valid/active pixels.
The value on the pin is 0 in progressive mode.
