APPENDIX 9
RECOMMENDED REGISTER VALUES
The ADV7172/ADV7173 registers can be set depending on the
user standard required.
The following examples give the various register formats for
several video standards.
In each case the output is set to composite/luma/chroma outputs
with DACs D, E and F powered up to provide 8.66 mA and
with the
BLANK input control disabled. Additionally, the burst
and color information are enabled on the output and the inter-
nal color bar generator is switched off. In the examples shown,
the timing mode is set to Mode 0 in slave format. TR02–TR00
of the Timing Register 0 control the timing modes. For a
detailed explanation of each bit in the command registers,
please turn to the Register Programming section of the data
sheet. TR07 should be toggled after setting up a new timing
mode. Timing Register 1 provides additional control over the
position and duration of the timing signals. In the examples this
register is programmed in default mode.
