Configuring special sync for FS, LS or CS

The special sync output can provide frame sync, line sync, or composite sync signals. The

output is controlled by setting parameters of these signals through the command line

interface. The following commands are used to set the special sync signal:

•

FSPG

- Frame sync

•

PSPG

- Probe signal

•

LSPG

- Line sync

•

CSPG

- Composite sync

Note: The special sync output is disabled whenever these parameters are set to zero.

A frame pulse can be generated and output at the beginning of each frame. In the case of

interlaced video, the frame pulse is output at the beginning of the blanking interval (of the

first field) that immediately precedes the top line of active video.

To configure frame sync on the special sync output:

1. Enable the frame sync by entering the following command:

FSPG 1

The values of the other parameters (

LSPG and CSPG

) do not matter once FSPG is

enabled.

2. Set the frame pulse polarity (either 0 for low or 1 for high) by entering the following

command:

FSPP 1

FSPG=1, FSPP=0

FSPG=1, FSPP=1
