Pixel Mode Selection
In Square Pixel mode, the number of Y, Cr and Cb components depends on the standard as shown in
Table 12
0: Normal Pixel mode (Default)
1: Square Pixel mode
Data is output from the STV2310 on the following pads: FIELD, VSYNC, HSYNC, PLLLOCK and
YCRCB[7:0]. It is synchronous to the CLK_DATA output clock either on the rising or falling edge depending
on this option.
0: Clock falling edge is active edge (Default)
1: Clock rising edge is active edge
Y/CVBS Input Selection
0: Y/CVBS1 input (Default)
1: Y/CVBS2 input
Pad Tristate Mode
The pad tristate mode depends on the chip I2C address.
If the I2C default chip address is chosen:
0: Output digital pads in Output mode (Default)
1: Output digital pads in Tristate mode
If the I2C spare chip address is chosen:
0: Output digital pads in Tristate mode (Default)
1: Output digital pads in Output mode
Note that only the following pads can be in Tristate mode: FIELD, VSYNC, HSYNC, PLLLOCK, CLK_DATA
and YCRCB[7:0]. The I2C pads are never in Tristate mode.
CVSB/S-Video Selection
The S-video mode notifies the STV2310 that the chroma and luma signals are already separated.
0: S-Video Input
1: CVBS Input (Default)
Vsync Search Mode and initial Free-running Mode
These bits provide the starting point for the Vsync extraction mechanism. 50-Hz or 60-Hz input standards
are expected. The options are to look exclusively for 50-Hz or 60-Hz standards (Forced 50 or 60) or to
search for all standards with a priority in the search mechanism (Auto 50 or 60).
00: Auto 50: Automatic search mode starting with 50-Hz standards. (Default)
01: Forced 60: Search mode forced to 60-Hz standards only.
10: Forced 50: Search mode forced to 50-Hz standards only.
11: Auto 60: Automatic search mode starting with 60-Hz standards.
. The output line locked frequency (CLK_DATA) will also change according to the standard.
