Horizontal AGC
This register provides a programmable delay for the HAGC pulse that control the sync
Pulse Programmable 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.
