The output formatter organizes the packing into the output
FIFO. The following formats are available:
Y-C
Y-C
formatting is controlled by FSI[2:0] 93H[2:0], FOI[1:0]
93H[4:3] and FYSK[93H[5]].
The data formats are defined on Dwords, or multiples
thereof, and are similar to the video formats as
recommended for PCI multimedia applications (see
SAA7146A). Planar formats are not supported.

EXPLANATION
FSI[2:0] defines the horizontal packing of the data,
FOI[1:0] defines how many Y only lines are expected
before a Y/C line will be formatted. If FYSK is set to logic 0
preceding Y only lines will be skipped, and the output will
always start with a Y/C line.
Additionally the output formatter limits the amplitude range
of the video data (controlled by ILLV[85H[5]]); see
Table 47.
