Hsync Timing Controls; Table 55: Hsync Default Timing; Table 56: Hsync Default Timing (Continued 1); Table 57: Hsync Default Timing (Continued 2) - Analog Devices ADV7850 Hardware Manual

All of these parameters are given as signed values. This means that rather than adjusting the absolute position of a signal, these
adjustments allow the user to advance (negative value) or delay (positive value) the respective timing reference signals.
