YUV output format
Sampling rate (changing this bit causes the register settings to be reinitialized):
0 = ITU-R BT.601 sampling rate (default)
1 = Square pixel sampling rate
YUV output code range:
0 = ITU-R BT.601 coding range (Y ranges from 64 to 940. U and V range from 64 to 960)
1 = Extended coding range (Y, U, and V range from 4 to 1016) (default)
UV code format:
0 = Offset binary code (2
s complement + 512) (default)
1 = Straight binary code (2
s complement)
YUV data path bypass:
00 = Normal operation (default)
01 = Digital composite output pins connected to decimation filter output, decoder function bypassed.
Both Y and UV buses output data at PCLK rate.
10 = YUV output pins connected to A/D output, decoder function bypassed. Both Y and UV buses
output data at SCLK rate.
11 = Reserved
YUV output format
:
000 = 20-/16-bit 4:2:2 YUV with discrete sync output (default)
001 = Reserved
010 = Reserved
011 = Reserved
100 = 10-/8-bit 4:2:2 UYVYUYVY
101 = Reserved
110 = Reserved
111 = 10-/8-bit ITU-R BT.656 interface with embedded sync output
