SYNC TIMING
DEPENDENCIES
The selected “active” edge of the external
timing reference signal RCV1 or RCV2 loads
the internal horizontal counter with the
HTRIG value. At the end of the line the
counter is automatically reset, and all timing
signals are in phase with the requesting
re-trigger. This horizontal counter also
defines the begin and end points of the raster
control output signals.
The effect of VTRIG for vertical
synchronization timing is very similar.
