External A/D width:
00 =
8-bit external A/D
01 =
9-bit external A/D terminal OEB is the LSB of the 9-bit input data
10 =
10-bit external A/D terminal GPCL is the LSB of the 10–bit input data, and terminal OEB is the
next–to–LSB (default)
11 =
Reserved
An external A/D converter can be used to provide up to 10-bit data directly to the digital data path. These
bits set the width of the external data path. External A/D access is enabled by register 20, bit 2. See
Figure 2–31 and register 20.
TV/VCR mode:
00 =
Automatic mode determined by the internal detection circuit (default)
01 =
Reserved
10 =
VCR (nonstandard video) mode
11 =
TV (standard video) mode
With automatic detection enabled, unstable or nonstandard syncs on input video will force the device into
VCR (nonstandard) mode. This turns off the luminance and chrominance comb filters and turns on the
chroma trap filter.
Disable color PLL:
0 =
Normal operation (default)
1 =
Force color PLL increment and genlock (GLCO) serial output to zero
Power down mode:
0 =
Normal operation (default)
1 =
Power down mode
