Horizontal AGC
Pulse Programmable
Start Time
This register provides a programmable delay for the HAGC pulse that control the sync
tip AGC in the A/D converters. The start time of the HAGC pulse is set from the detection
of horizontal sync in the video data. HAGC is programmable in CLK increments and has
a fixed 1 clock delay following the falling edge of horizontal sync. This is the upper byte
of the 10-bit word.
