Bit Field Type Reset Description
31-27 Reserved R 0h
26-16 SRC0_NUMPIX R/W 0h
Number of expected pixels on Source Number 0. The
Port_b_src0_size interrupt will trigger if a line is encountered that
differs from this pixelcount.
15 Reserved R 0h
14-13 ANC_CHAN_SEL_8B R/W 0h
In 8b mode, Vertically Ancillary Data typically resides in the Luma
sites. This bit allows vertical ancillary data to be extracted from the
chroma sites instead.
00 = Extract 8b Mode Vertical Ancillary Data from Luma Sites
01 = Extract 8b Mode Vertical Ancillary Data from Chroma Sites
10, 11 = Extract every single sample of vertical ancillary data.
The output line is twice as wide as the other modes.
12-11 Reserved R 0h
10-0 SRC0_NUMLINES R/W 0h
Number of expected lines on Source Number 0. The
Port_b_src0_size interrupt will trigger if a field/frame is encountered
that differs from this linecount.
