TIMING REGISTER 1 (TR17–TR10)
(Address (SR4–SR0) = 0BH)
Timing Register 1 is an 8-bit-wide register.
Figure 53 shows the various operations under the control of
Timing Register 1. This register can be read from as well writ-
ten to. This register can be used to adjust the width and position
of the master mode timing signals.
TR1 BIT DESCRIPTION
HSYNC Width (TR11–TR10)
These bits adjust the HSYNC pulsewidth.
HSYNC to FIELD/VSYNC Delay (TR13–TR12)
These bits adjust the position of the HSYNC output relative to
the FIELD/VSYNC output.

HSYNC to FIELD Rising Edge Delay (TR15–TR14)
When the ADV7172/ADV7173 is in Timing Mode 1, these bits
adjust the position of the HSYNC output relative to the FIELD
output rising edge.
VSYNC Width (TR15–TR14)
When the ADV7172/ADV7173 is configured in Timing Mode
2, these bits adjust the VSYNC pulsewidth.
HSYNC to Pixel Data Adjust (TR17–TR16)
This enables the HSYNC to be adjusted with respect to the pixel
data. This allows the Cr and Cb components to be swapped. This
adjustment is available in both master and slave timing modes.
