TR0 BIT DESCRIPTION
Master/Slave Control (TR00)
This bit controls whether the ADV7170/ADV7171 is in master
or slave mode.
Timing Mode Control (TR02–TR01)
These bits control the timing mode of the ADV7170/ADV7171.
These modes are described in more detail in the Timing and
Control section of the data sheet.
BLANK
Control (TR03)
This bit controls whether the
BLANK
input is used when the
part is in slave mode.
Luma Delay Control (TR05–TR04)
These bits control the addition of a luminance delay. Each bit
represents a delay of 74 ns.
Pixel Port Select (TR06)
This bit is used to set the pixel port to accept 8-bit or 16-bit
data. If an 8-bit input is selected the data will be set up on Pins
P7–P0.
Timing Register Reset (TR07)
Toggling TR07 from low to high and low again resets the inter-
nal timing counters. This bit should be toggled after power-up,
reset or changing to a new timing mode.

TIMING REGISTER 1 (TR17–TR10)
(Address (SR4–SR0) = 08H)
Timing Register 1 is a 8-bit-wide register.
Figure 44 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
VSYNC
/FIELD 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 ADV7170/ADV7171 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 ADV7170/ADV7171 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.
