To force the pass through mode, use the PASSTHROUGH_EN bit in the
To shift the external Hsync pulse, use the HSYNCSHIFT_DEL[1:0] and HSYNCSHIFT_EN bits in
the
Cr Cb attenuation are controlled by the DDECCONT37 and the DDECCONT38 registers.
The output blanking modes are controlled by the OUTBEHAV_BLANK2 and OUTBEHAV_BLANK1
bits in the
Output clipping is controlled by the DDECCONT18 register bit [2].
The PLLLOCK, HSYNC, VSYNC and FIELD pins may have bus extension functions. This is done by
programming the OUTBUS [7:0] bits in the
The PLLLOCK pin has a second alternate IRQ (Interrupt Request) function, selected by the
PLLLOCKIT_EN bit in the
By default, the PLLLOCK, HSYNC, VSYNC, and FIELD pins are used for their primary functions.
VBI Data Slicing and Insertion
The following standards are supported by the VBI Data Slicer (see
is embedded in the output stream, using the intervals between the End of Active Video (EAV) and
the Start of Active Video (SAV) codes of each line and formatted according to the ancillary
sequences in compliance with specification ITU-R BT.656. VBI data is inserted in the Output FIFO.
