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 posi-
tion of the master mode timing signals.
TR1 BIT DESCRIPTION
HSYNC
Width (TR11–TR10)
These bits adjust the
HSYNC
pulsewidth.
HSYNC
to FIELD/
VSYNC
Delay Control (TR13–TR12)
These bits adjust the position of the
HSYNC
output relative to
the FIELD/
VSYNC
output.

HSYNC
to FIELD Delay Control (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.
