ADV7160/ADV7162
3. CR45 of Command Register 4 is set to Logic “0” during the
following vertical retrace and the acquired signature is read.
At least 20 clock cycles should be allowed for the final pixels
of the frame to travel down the pipeline of the ADV7160/
ADV7162 before the signature clock is disabled.
The signature analyzer is read from control registers 010H to
013H. These are read only 10-bit registers. The access to these
registers depends whether the part is in 8-bit or 10-bit data bus
mode and operates in the same way as accessing the color palette.

APPENDIX 5
SIGNATURE ANALYZER
Signature Register
The ADV7160/ADV7162 contains onboard circuitry that enables
both device and system level test diagnostics. The ADV7160/
ADV7162 has a signature analyzer in the pixel datapath, just
before the DAC decoders. The signature analyzer consists of a
33-bit linear feedback shift register. The 30-bit pixel value is
fed as a parallel input into the analyzer. The signature analyzer
only accumulates a signature during active display time when
BLANK
is high. Bit CR45 to CR47 of Command Register 4
control the signature analyzer. When CR45 of Command Reg-
ister 4 is set to Logic “1,” the clock to the signature analyzer is
enabled. Toggling CR46 low and then high resets the signature
analyzer. This is done to give a known starting point before ac-
quiring a signature. CR47 of Command Register 4 controls the
feedback inputs to the analyzer. When CR47 of Command
Register 4 is a Logic “0,” the feedback is disabled and on each
clock cycle, the 30-bit pixel value is latched directly into the
analyzer. To acquire a signature as the analyzer is clocked,
CR47 of Command Register 4 is set to Logic “1.” To acquire a
signature the following procedure must be followed:
1. CR45 and CR47 of Command Register 4 are set to Logic
“1” during vertical retrace and CR46 of Command Register
4 is toggled to reset the analyzer.
2. A signature is acquired during the following active screen.
